Popup window to remain visible

I would like the popup window notification to remain on my screen until I dismiss it!!

If I have been away from my desk - more than 3 minutes - I would still be aware of the arrival as the popup would still be visible.

Is that possible???

It depends on what notifications you are using.

If you aren’t using system notifications (1), you can untick the option just above that so the popup is not hidden:

If you are using system notifications (1), the popup is handled by your OS. You change that here in Windows 11 for up to 5 minutes:

After that you will find it in the Windows Notification Centre.
