My design system file is empty, the pages are gone and I cannot add any new pages

I was taking a tutorial and after setting up my design system, I moved on to publish it, attach it and create my prototypes. When I tried opening the file again, I noticed all the pages were gone. The library is still published, but I need to make some changes and I cannot find any of the pages. Please help!

Expand the list of pages by clicking on the name of the current page (“Welcome”) in the left panel.

I feel so silly for missing this. Thank you, you’re a gem!
