ProBuilder Sample Scenes

I feel like I'm taking crazy pills here. I've installed the latest version of ProBuilder, and it's in my Packages folder in Unity. However, the Samples folder isn't showing up. If I view the folder in my File Explorer, I can see that there's a Samples~ folder.





Any suggestions on what I can do to make this folder show up in Unity? I'd really like to try the runtime examples. I've tried opening the scenes directly from the Samples~ folder in the folder explorer and it didn't work either.
