Thanks, I was not aware of this. It appears to use the Windows global mic control API, which is pretty straight-forward to even implement by yourself programmatically. Unfortunately, as Teams does some magic with the mute, if you have an external program, but still use Teams app to mute your conference call after call has already started, the state will not propagate to the external program, i.e. you cannot reliably show on the button whether the mic is muted or not.
