how to thank killer after they let you escape?

hi, so i'm a fairly new player, and during one game i was the last survivor remaining, so the gate opened. while i was opening the gate, the killer (michael myers) stood there to let me open it, and allowed me to escape. before escaping completely, i turned back to the killer and crouched several times and nodded at them. this was meant to thank them. i even thanked them for letting me escape in the end game chat. i later found out that teabagging at the exit gates is considered toxic and rude. so is basically any in game gesture apparently. my question is: is there any way to thank the killer without coming across as rude? would my gesture have been considered rude in its context?
