```

hs.loadSpoon("MicMute")

binding = { toggle = { {"ctrl", "alt"}, "m" } }

spoon.MicMute:bindHotkeys(binding)

```

You'll have to add the MicMute spoon which just mean downloading the zip here, unzipping, and opening the .spoon. https://www.hammerspoon.org/Spoons/MicMute.html

What do you mean? Like muting the entire application so no sound comes from Teams or muting yourself while on a call? For the latter, I thought 'Option + Space' worked (or used to)?
