Hello @scott_groomes ...
There are a couple of things to know about the "Notifications" screen within Canvas. When any user is on the "Notifications" screen, he/she can hover over any of the text in the left-most row, and a little pop-up will show that gives some additional information that may be of help. This is detailed in the How do I set my Canvas notification preferences as an instructor? Guide. (Look under the "View Notification Details" heading.) Also, in this Guide that I've linked for you, there is a blue box at the top of the screen. In the first paragraph of that blue box is a link to a PDF file. That PDF gives even more detail about each of the rows in the "Notifications" screen.
Regarding Zoom... I'm not completely sure that's correct. We have Zoom integrated with our Canvas environment as well. We also have Zoom configured to automatically send a message (via the Canvas Inbox) to students any time an instructor creates, edits, or deletes a Zoom meeting. So, if this is similar for you (and what you are referring to about a connection to Conversations and Zoom), then I *think* I'd agree there...but if you don't have Zoom configured like this, I'm not sure this is correct. I could be 100% wrong on this, though.
I hope some of this will be of help to you. Sing out if you have any other questions...thanks! Take care, stay safe, and be well.
