Where to put old Photos Library in Catalina?

I rescued data from an obsolete MacBook Pro's corrupt disc - I now have an external hard drive with a folder tree like this: Users > name > Pictures > Photos Library. The Photos Library file is 106 GB, and I'd like to import it into a new MacBook Air running Catalina 10.15.5.

I don't find where to import the Photos Library file in Catalina. My Finder window has Favorites (AirDrop, Recents, Applications, Desktop, Documents, Downloads) and Locations (External HardDrive, Network). But no navigable folders for the hard drive like I'm used to.

Can someone point me where to import these photos in my new Air? Thanks!
