A userscript to clean up those annoying "Launch Meeting" tabs Zoom likes to open. I'm not positive I've captured every path variation Zoom uses so let me know if you find one that doesn't work.

const maxDelay = 30 * 1000; // ms
const falloffFactor = 1.2;

let delay = 200; // ms
const doClose = () => {
  if (window.location.hash.includes('#success')) {
    window.close();
  }
  delay = Math.floor(Math.min(delay * falloffFactor, maxDelay));
  setTimeout(doClose, delay);
};
