Unmute mic temporarily with a quick shortcut like "space press"
Unmute mic temporarily with a quick shortcut like "space bar" and then remute (Feature similar to Zoom)
Frank R. commented
The space bar unmute in Zooms basically works as a "Push to Talk" function - it unmutes as long as the button is pressed, and mutes again when lifting the finger off the button.
its really a good option and should avalable as soon as possible.
its there in webex, zoom etc...
And also unmute via long press on iPad/iPhone app
