About ten minutes ago, a gray notification popup appeared in the upper right corner of my desktop, something about not using my Apple ID. Before I could see what it was, it retracted into the "side" of the desktop again, and I cannot locate it.
In Sonoma, notifications were in the notifications but where do I find messages like that in Sequoia? It's not in the Notification Center, and I can't find a widget to show them, nor is it in the Console.
Thanks for any help.
