iCloud Photos not listed as my Photos Library.photoslibrary
When I try to attach a photo to an email, and select "Media > Photos" from the "Choose File" popup window, I get an empty window with the message "Open Photos to see your photos in this list." My photos are all stored on iCloud and not locally. I have no Photos Library.photoslibrary stored locally. How can I setup my MBP running Monterey to access iCloud-stored photos?
