How would I hide/change the 'appearance' of names in the new Chat?

Why

With the new chat I'm trying to merge/port features from the custom chat that I made for one of my games(since I like the new chat much better).

One of the features was covering the names of the chatter with another variable(but sending it as the player) for everyone. Basically there's a variable that determines the 'Identity' of the character. Identities are constantly being switched around, and it kind of spoils the fun if the 'Identity' of the target just shows as the normal player.

What I already know

just the stuff to change it - but I don't know where to change it.

--(Location of final send) = identity.Value

TLDR Where can I change the name of the sender in the chat.

One way you could solve this is to remove the chat entirely and replace it with a custom chat made with guis. You can find some nice tutorials online. I don't have time to explain it here. Now, you wouldn't put a GUI for where their username is displayed like the tutorials tell you. I hoped this helped.
