Question about Chat / Communication for players without mic

Hello !

I’m making a map In Fortnite UEFN where players have to complete mini-games while there is a among them killer/s like in among us. As im making a map i by play testing it noticed that a crucial part is player communication. I don’t feel great isolating most of players playing the map by not giving an option to communicate. To solve that I had idea Hat emoji system. I read the text chat is not allowed so instead by adding chat add a emoji system witch is restricted to things like :raised_hand:, :+1:,:-1: and they would show above players head.

Would the map be accepted if it had such player communication or not ?

If not could is there any systems that are allowed for players without microphone to communicate in any way ?
