in-call disappearing text messages for ppl who are muted (club penguin style )

I love to contribute little throwaway chats when I'm muted, but don't love to clog up a dedicated text chat or need to click away from the video call to read them, this could be a cute feature!!  it could be optional/ something servers have to enable as I'd imagine it might not scale well for giant servers, but yeah that is my little idea!! thanks for taking ur time to read it!
