Need to unmute while watching screen share

[jllogan]

I am often unable to find the unmute button to speak during someone else's screen share.

For every single meeting, I need to take notes on one screen while watching a screen share on the other.

The mute functionality is only available on Zoom's  video window, which is *never* on top because we *never* use video.

Please provide a way to unmute in this situation.
