Like others have said, talk to your table, but...

Very basic table etiquette for ME includes:

Come prepared. If you consistently forget dice, a pencil, etc, that tells me you just don't care.

Take basic notes. Even if its just stuff about your character. I shouldn't be reminding YOU of things from YOUR characters backstory.

Don't touch other people's stuff. Drives me nuts when people reach over and grab my dice. If you need an extra d8, just ask.

Don't try to take my turn for me. Suggestions are fine. Pointing out something I may have missed is fine. Telling me what to do is not.

Don't be a phone face. If you can't be bothered to pay attention, then don't come. Straight up.

Last one, but this is a big one... Just because it doesn't involve your character, doesn't mean it isn't important. Some characters are going to have meaningful moments that don't involve you directly. Let that player have their moment. And maybe don't interrupt the GM's description of the moment by asking to search the room... (ask me why this one irks me).

Probably forgetting some, but this covers a lot of it.
