What is the window class name for 'Update Required'?

I'm trying to automate Zoom launching process with python in Windows 11, and I noticed a popup that said update was required before joining a conference that I think looked like this: 

What is the window class name for this popup? I closed down the popup because the conference had already started before getting the name. Now I can't reproduce this popup. If any of you are familiar, I need the output of win32gui.GetClassName(win32gui.FindWindow(None, 'Update Required'))

EDIT:

On the second thought, I think I want to reproduce this situation. Can anyone tell me how to do so as of today?
