Help EJECTING iPhone from Mac's "Photos" app.

I do not use iCloud for my iPhone photos. I manually remove photos from iPhone 13 and transfer to a Mac running OS 13. But once the photos are transferred to "Photos" app, I cannot see any way to safely EJECT the phone.

My solution:

I eject it in a Finder window, but its still recognized inside "Photos" app. The "help" section inside Photos offers this advice, but when I try it, I do not see "UnMount" is it Safe to unplug at this point? Thanks, Deb
