Passport Ultra/Mac - How to see photos TimeMachine backedup?


Using Ultra Passport 2TB for MacBook Pro running Mojave, I have made my first backup and can see various documents when checking b.u., but I can’t see or verify that my photos are backed up. Clicking on Photos in the list of b.u. items only shows the app and its size. How can I see or select photos? Will appreciate any help!
