// I just pasted this together from things found scattered around the internet. Starting with: https://github.com/Emperorlou/MidJourneyTools
//
// To enable periodic downloading of newly-created images, go to a 'recent creations' page, and add "&autosavetimer=60" to the URL;
// something like: `https://www.bing.com/images/create/-/1234?autosavetimer=60`.
//
// This implementation is designed to be left unattended - periodically reloading itself. If you click a link then `autosavetimer=` will
// be removed from the URL and the script will stop working. Removing `?*autosavetimer=*` from `@match` above _might_ work, but it's not
// well tested at this stage.
