This script allows you to leave Google meets when others are leaving themselves. Just enter the meet, set the number of participants for when you want to leave, and the script will leave for you automatically once enough people have left.

IMPORTANT! - If You want this to work when you tab switch, then install the extension "Always active Window - Always Visible".
Click it --> This can read and change site data --> On meet.google.com
Why? Because it will make the meet tab always active (and the default setting makes all your tabs active, which is resource-intensive)

Included is an auto microphone and camera disabler because why not.
