Simple, easy to use and works well. Very well done.
I have been working on an automation solution on my Mac that involves downloading .ics files from MyChart, use a script via Google API to inject a guest list, and using Automator to trigger a folder action to run my script. The final issue was getting the downloads into a folder so that my script could run without triggering on every download. This extension is the missing piece! Now I don't have to rely on my adhd brain to invite my spouse to my medical appointments.
