Cannot find photos library in Finder

I was hoping to export some of my photos from my Photo library on my Mac into Adobe Lightroom Classic and my photo library isn't appearing in the file structure. If I click into the Pictures folder (where it used to sit), all I see is a myriad of "iPhoto Library Recovered Photos" folders (which I'm not sure how they got there tbh). This is also the case when I look in Finder.

Any idea why this might be or how I can fix this?

I'm currently running macOS Catalina 10.15.5, on a brand new MacBook Pro.
