Pre-Flight Checklist

• I am not asking a question => use the Discord if you are
• I have checked that someone else has not reported this using the search bar
• My feature request is not one of the commonly suggested features: iOS app (it's already being development)

Is your feature request related to a problem? Please describe.

I've been using this mod with a group of 13-15 friends for the last 3 hours and we've been enjoying it greatly, but we've had at least 10 situations where 4 different people who use voice activation didn't realize they were muted for the last few minutes, just because there is no sound confirmation for a mute/unmute.

Describe the solution you'd like

It would be lovely to have 4 sounds for mute/unmute/deafen/undeafen, like Discord has for example :)

Describe alternatives you've considered

Well the default right alt bind is kind of problematic since we use it for polish characters when typing, but even if we switch the binding to some exotic key like Break or whatever, there's always gonna be this one person getting upset about accidentally clicking it at some point in the game. And the key to mute yourself is a pretty useful one so it's nice to have it in a handy place!

Additional context

Thanks much :)
