Mic Toggle Notification

[Jabberhopper]

Is your feature request related to a problem? Please describe.
im using the button on the index hmd to toggle my microphone,
(which i set up through vrDashboard bindings after enabling OVR's "Enable System Button Binding" toggle).
There is no indication if my mic is on or off

Describe the solution you'd like
an option in the audio section, similar to "Show Notification" for push to talk
either a sound, or a visual showing microphone getting muted / unmuted

Describe alternatives you've considered
currently i have to guess if my mic is muted or not, or check the steam overlay,

Additional context
first time using feature request on github :)
