Jesus took Baptism, which was a cleansing ritual it removed dirt from the body and transformed it into something greater. He transformed it into an appeal to God.
just brainstorming but I thought baptism was an appeal from God for us to change, to prepare ourselves, for His presence, as John ministered in that fashion(John"s baptism). Not sure it was an appeal from our part, but a surrender to His washing, on His say so (to do).
"we see that the use of water to symbolize cleansing and consecration is very much a Jewish concept, repent of sin and be symbolically cleansed in the Jordan River. "
BINST GEVOREN A GOY! “You’ve become a Gentile!” We Jewish believers in Yeshua often encounter this accusation after we’ve been baptized.

An appeal means to ask a higher court for a reversal of a previous decision. When you are Baptized you are condemned because you inherited original sin. Original sin is the previous decision made by God. You are asking him to reverse His previous decision and make you born again.
Think about it if you are born again before Baptism what previous decision, that God placed on you, are you appealing that God reverses?
But I see you speak of the apostles baptizing after Pentecost.
As to the word appeal, many translations have other wording , such as “answer”, response, pledge, examination.
For sure at some point salvation is an appeal, and at some point it is a confession, an answer.
“Who so cries out to the Lord shall be saved”
“And with the mouth confession (of His salvation) is made unto salvation”.
You are right back to the age old dilemma, of baptismal regeneration, or a believers baptism.
So as to your question, for me the baptism is signifying the appeal one has already made in their heart for salvation,
and the answer received, the assured gifting of a clear conscience, and not because of my baptism, but because of what Christ did , dying and resurecting, having pleased the Father, as I do now placing my faith and confession of, in Christ.
The clear conscience is due to His resurection, not my baptism, though it signifies my union with Christ in His death
If you use your word “appeal”, as in a question to God, where is the answer? This would lead to think that Peter leaves the door open to one already knowing the answer, before baptism, even allowing the baptism to signify what has already happened…a clean conscience.
So then how does baptism save as Peter alludes? I would think by the obedience to confess with the mouth the Lord in the waters of baptism, of what already has happened in the spirit.
