Final Cut Pro “Apple Loops” folder missing in Finder, but actually exists

I had been using Final Cut Express on my MacBook Pro starting in 2009. In April of 2024 I upgraded and the folks at the Apple store transferred all of my old computer onto the new MacBook Pro. Soon after I purchased a new version (11.0) of Final Cut Pro. In the music window there was a large amount of built in music, many short clips that were royalty free. Just a few weeks ago I found I couldn’t find any of my music on FCP . I can’t remember if it was about this time that I upgraded to Sequoia. Anyway I contacted Apple Support and they were able to reconnect the music that was in my music folder. I am still not able to find the built in music. I spent about 45 minutes on the phone with Apple Support, and despite really trying the tech was not able to help me. He initially said FCP didn’t come with built in music, but I have used it. It either came from the old FCX or the new version. I sure want to reconnect it. It sounds like a Library issue but I have no idea ho to reconnect it.
