Were did the "notify me when available" function go?

I am running Version: 5.17.2 (29988) of the Zoom desktop client and cannot for the life of me, figure out what happened to the  "notify me when available" function. I used to just right click on someone's name and would have the option to get a notification when they got off the phone. Please tell me this feature was not removed! It was so helpful and probably one of my most used functions!

I also noticed we are no longer able to "check for updates." How will we know we are running the latest version and how can we troubleshoot when we have issues? We used to check for updates whenever we had problems in our office and installing the latest updates would almost always resolve the problem. Now we cannot do that either. Not liking these new updates, Zoom!
