Change mute/unumte display
If a participant is muted and he wants to unmute himeself, there are 2 separate cases:
- The participant is moderator -> he can unmute
- The participant is not moderator -> he can't unmute and a pop-up will be displayed on the unmute button (like "You have been mute by a moderator")
The mute buttons (in participant overlay and call bar) shoud display the same state
