How will zoom notify me when someone is avalible?

When I asked "How does Zoom notify you when a contact you set to "Notify when available" becomes available?", I was sent to this answer posted on ‎2022-12-13 11:04 AM by Bort.  While his response: "you also need to be signed-in to your account, as the notification will appear there" is relevant, it does not answer the question of HOW the notification will be made.  Bort further states that: "If you are not signed-in to the app, Zoom won't be able to notify you by other means. "  What I was looking for was, by what other means the notification will be made.  Since this answer was unobtainable through the Zoom Community, I had to perform my own test of the function. 

When I set one of my contacts, who was currently offline,  to "Notify when available", then asked her to log in, I got the information I was asking for. A small white rectangular window containing the blue Zoom logo and the name of the contact I was looking to be notified about, appeared at the bottom right of my screen, accompanied by a small 'ding' sound from my speaker. THAT was the information I wanted so that I would know what to expect when one of my contacts came available at a time unknown to me. I hope this clarification helps the next person understand what will actually occur when they have a contact log in after setting them to to "Notify when available".  It IS a very useful feature.  Thanks, Zoom!
