[Microphone Indicator] Show OSD when app starts using muted microphone
When an application starts using the microphone but it is muted, show the OSD as a reminder.
It won't show again unless the microphone was unmuted inbetween.
I have my mic muted most of the time but sometimes I want to send a voice message and then forget I am muted.
