Alarms don't work unless Gnome Clocks is set to run on startup
I ended up missing alarms quite a few times before I ended up using the following as a solution: After this, I would close the window, and continue my work. The application's background process would continue and the alarms would work. I don't think this should be necessary. Personally, I would be fine with the background process being registered as a start up task once the program is installed.
I'm using Fedora 35 + Gnome 41.2 + Clocks v41
