// Main Feature - Google Meet Auto Leave
// 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)


// window.trustedTypes.createPolicy('default', {createHTML: (string, sink) => string});
