You can control the mute in software using the Arduino USB keyboard library, then just send the appropriate key combination when the button is pressed:

For MS Teams, you send Ctrl+Shift+M (Cmd+Shift+M for Mac) For Google Meet you send Ctrl+D (Cmd+D for Mac) For Zoom, you send Alt+A (Cmd+Shift+A for Mac)

Note that unlike Telephony devices, which can return the status of the mute on the computer, there is no way to tell if the software itself is muted.

Thats a subpar solution as it requires teams to be in focus.
