missing Logic Pro X and GarageBand music

I can get my Photos, iTunes and Sound Effects to show up in Final Cut Pro but none of my Logic Pro X music files show up, nor do any GarageBand music files. Actually I see 5 GarageBand files and below the list is an message that says "6 files are missing iLife preview and unavailable". iLife?? I am on Mojave and can't/won't update to Catalina if that makes a difference. Any way to get my many gigabytes of Logic Pro (I have downloaded a lot but not all of the sound files) and GarageBand sound files to show up? There is nothing available in "Download Additional Content" in the software update section.

Where are you saving your Logic and Garage band compositions to when you Bounce them out?

I'm not doing anything in Logic or GarageBand. I am wanting to be able to see, in FCP, the sound files that come with the programs with Logic and GarageBand. FCP gives me access to all my iTunes sound files as well as my Photos so I can use them in FCP projects. FCP also shows GarageBand and Logic Pro X in the same place as if I should be able to view the sound files that come with those programs. It even shows me something like 6 of the Garageband files and I -assume- it should allow me to use the other Garageband and Logic Pro X sound files but they do not show up.

Those show you songs you've recorded in those apps and saved to the locaiton it reads. They do not show you all the loops and such that come with those apps.

There is a workaround to enable FCPX to show GarageBand Loops. Here is a Ripple Training video showing how to do that:

As for Logic Pro X, there are ways to create aliases and place them in the appropriate path so FCPX sees them, but I seriously doubt you'd want 45+ GB of sound files and loops populating in your FCPX sound library.

Yeah, if you want to work that intensively with that massive of a loop library, you really need to go to GarageBand and Logic to do that.
