Google Calendar does not give notifications like I would expect
I have enabled notifications in Google Calendar and allowed them in Firefox browser for MacOS. But I am still not getting popups like I would expect. The sound plays notifying me I have an upcoming event but there is nothing visual to tell me this other than the sound icon that appears during the sound on the tab. Is this how Google Calendar is supposed to work? Tab switching is also enabled but I don't get switched to Google Calendar. I leave it open all the time in a pinned app, so I don't see why there would be an issue here.
Please find my attached images where I think things are correctly set up.
