blue thumbs up

A sticker in messenger used to indicate, "I have stopped talking. You should also stop talking."
Although it also can imply that you like something, so it's still polite.

Friend: Are we still on for *that stupid event that you haphazardly agreed upon* tomorrow evening?
You: *Blue thumbs up*
Friend: Great! See you there!
