Push to Talk Keybind - Steam Lobby

I posted this in the official Discord bug reports as well, but wanted to post here to be sure it reaches the developers. When in lobby on Steam voice chat defaults to “T” as a keybinding and cannot be changed. I already use T for my Discord push to talk, and have for years. This means my teammates hear me talking twice in game with no way for me to change the keybind or adjust the output volume so it’s super loud. This was added with the big patch for the latest event and must be an oversight. Also my teammates can mute me in lobby by clicking my player card and clicking mute, but it unmutes me after ever single match so they have to re-mute me after each game/new play session. Please add a way for us to adjust the push to talk keybinding in lobby!
