The angel of the Lord was worshipped by several of Gods chosen in the OT.
Gideon refers to the Messenger of YHWH as adoni.
Since the Messenger of YHWH is YHWH demonstrates Gideon was referring to YHWH as adoni.
Judges 6:11-23
11 The Messenger of the Lord came and sat under the oak tree in Ophrah that belonged to Joash from Abiezer’s family. Joash’s son Gideon was beating out wheat in a winepress to hide it from the Midianites.
12 The Messenger of the Lord appeared to Gideon and said, “The Lord is with you, brave man.”
13 Gideon responded, “Excuse me,
sir! But if the Lord is with us, why has all this happened to us? Where are all the miracles our ancestors have told us about? Didn’t they say, ‘The Lord brought us out of Egypt?’ But now the Lord has abandoned us and has handed us over to Midian.”
14 The Lord turned to him and said, “You will rescue Israel from Midian with the strength you have. I am sending you.”
15 Gideon said to him, “Excuse me, sir! How can I rescue Israel? Look at my whole family. It’s the weakest one in Manasseh. And me? I’m the least important member of my family.”
16 The Lord replied, “I will be with you. You will defeat Midian as if it were only one man.”
17 Gideon said to him, “If you find me acceptable, give me a sign that it is really you speaking to me.
18 Don’t leave until I come back. I want to bring my gift and set it in front of you.”
“I will stay until you come back,” he said.
19 Then Gideon went into his house and prepared a young goat and unleavened bread made with 18 quarts of flour. He put the meat in a basket and the broth in a pot. Then he went out and presented them to the Messenger of the Lord under the oak tree.
20 The Messenger of the Lord told him, “Take the meat and the unleavened bread, put them on this rock, and pour the broth over them.” Gideon did so.
21 Then the Messenger of the Lord touched the meat and the bread with the tip of the staff that was in his hand. Fire flared up from the rock and burned the meat and the bread. Then the Messenger of the Lord disappeared.
22 That’s when Gideon realized that this had been the Messenger of the Lord. So he said, “Lord God! I have seen the Messenger of the Lord face to face.”
23 The Lord said to him, “Calm down! Don’t be afraid. You will not die.” (GW)
Verse 12 - The Messenger of YHWH appears unto Gideon.
Verse 14 - The Messenger is described as the Lord (YHWH) which spoke unto Gideon.
Verse 17, 18 - Gideon asks "Him" (the Messenger of YHWH) not to depart.
Verse 18 - The Messenger of YHWH says He will wait until Gideon returns.
Verse 19 - Gideon brings out the food unto the Messenger of YHWH under the oak tree. This is where the Messenger of YHWH was originally (verse 11).
Verses 20-22 - Describes what the Messenger of YHWH did to Gideons' offer.
Notice also in verse 22 that Gideon realized that the Messenger to whom he referred to as "sir" (adoni) in Judges 6:13 was in fact YHWH! By seeing the Messenger (YHWH) face to face Gideon was in fear that he would die (cf. Exodus 33:20). This is why in the very next verse (23) YHWH assures Gideon that he will not die even though Gideon saw YHWH face to face.
The Angel of the Lord in the OT was the pre incarnate Son which is why He is identified as YHWH and worshiped as God unlike the created angels who are not worshiped.
Gen 22:11-14
But the angel of the Lord called out to him from heaven, "Abraham! Abraham!"
"Here I am," he replied.
12 "Do not lay a hand on the boy," he said. "Do not do anything to him. Now I know that you fear God, because you have not withheld from me your son, your only son."
13 Abraham looked up and there in a thicket he saw a ram caught by its horns. He went over and took the ram and sacrificed it as a burnt offering instead of his son.
14 So Abraham called that place The Lord Will Provide. And to this day it is said, "On the mountain of the Lord it will be provided."
Exodus 3:2, 5
And the angel of the LORD appeared unto him in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed…And he said, Draw not nigh thither: put off thy shoes from off thy feet, for the place whereon thou standest is holy ground.”
Well the main function or a general definition of a "shaliach" is as follows:
A shaliaḥ (שָלִיחַ; pl. שְלִיחִים, sheliḥim) in Halakha is a Jewish legal or agent. Accordingly, a shaliaḥ performs an act of legal significance for the benefit of the sender, as opposed to him or herself.

A Chabad shliach (שליח, pl. שליחים/שלוחים, shlichim/shluchim) is a Chabad member sent out to promulgate Judaism and Chasidut around the world. Chabad shluchim today number about 4,000 worldwide, and can be found in many of even the most remote worldly locales.

Now, I am bringing this up for a very good reason and I want to cut to the chase of my point in this little exercise. The basic job of a "shaliach or the definition is an agent sent on a specfic mission to represent the interst of someon else. In short there are restrictions to the function of a shaliach and I will give you the best example.
Now, you have at Genesis 16:7 the very first appearance of the angel of the Lord. If you read the context from verse 7 to Genesis 17:1-2 you will discover that the Lord God Almighty is the speaker even though the the angel of the Lord is actually speaking. At verse 10 the angel of the Lord says that He will greatly multiply the descendents of Hagar. Then at Genesis 17:1 and 2 it's the Lord God Almighty who will multiply his descendents. You cannot get away from the fact that the same being is taking in the passages. Even at Genesis 16:13 Hagar says I have see the Lord God and am still alive.
Now, lets jump to Genesis 22 where God is going to test Abraham. You have the Lord God Almighty speaking from Genesis 22:1-10. There is no question about this fact. At verse 11 it states, "But the angel of the Lord called to him (Abraham) from heaven and said, "Abraham, Abraham!" And he said, "Here I am." Then at verse 15 the angel of the Lord called to Abraham from heaven a second time." (Note: why does the angel of the Lord have to call out for God Himself a second time from heaven?) Is not the Lord God Himself capable of calling out from heaven Himself. I mean He did call out from heaven at Mark 1:11. He did not need the so-called shaliah then.
After the angel of the Lord calls out from heaven the second time which is Genesis 22:15 here is what this so-called shaliach/emissary says, "By Myself I have sworn, declares the Lord, because you have done this thing, and have not withheld you son, you only son. Indeed, I will greatly multiply your seed as the stars of the heavens, and as the sand which is on the seashore etc."
So you see from following the sequence of events a shaliach is limited or he can only do so much on behalf of the sender. He cannot swear an oath for the sender as you see the scriptures say. He cannot multiply the seed of anyone as you see the scriptures say.
Not only that but the real kicker of all of this is found in the NT at Hebrews 6:13. The writer of the Hebrews states, "For when God made the promise to Abraham, SINCE HE COULD SWEAR BY NO ONE GREATER, HE SWORE BY HIMSELF, VS14, SAYING, "I WILL SURELY BLESS YOU , AND I WILL MULTIPLY YOU." This text is referring back to Genesis 22 and Abraham. A shaliach cannot swear an oath on behalf of the sender and it even says God swore by Himself. In short, the shaliach argument will not work and I maintain that the messenger of the Lord is the pre-incarnate Jesus Christ
hope this helps !!!
