Sure this works!
Simply checks to see if a google meet room is open, and notifies you/bring you to the join page once it is. Open the script and change the your_classcode to your classcode. If you use multiple rooms, you'll need to install the script more than once. Other than that, just make sure you reload meet.google.com once you enable the script. I suggest that you only start the script running when you need to, since having it running all the time could flag you for misuse.
