How do I unhide "ALL" games/apps?

I know how to get to my hidden games, that's not the issue. Please read carefully to understand.

In previous versions of the Xbox dashboard, while in the Game Pass section, you could choose to hide games. I did this with a LOT of games that I didn't feel I'd be using Game Pass for, at the time I saw no issue with this. Fast forward to the current versions of Xbox and Game Pass in the dashboard is handled differently. However, if I buy a game that was previously hidden on Game Pass it's still hidden from my "ready to install" category.

Now, this is where it gets more complicated. I just bought Resident Evil 7+8 on the Xbox store. Previously I'd hidden 7 on Game Pass in that old dashboard version (I was planning on getting it for PlayStation at the time). Now though, I cannot find it in "Ready to Install" or "Hidden" in my library.

My assumption is that the version I hid is a particular version of the game that is no longer listed. This isn't anything new, I had major issues with the 'vanilla' version of Dead Rising 3 being de-listed and honestly just ended up buying the 'apocalypse edition' again (despite already buying all the DLC as well).

My point is, there are game(s) not showing in my hidden list that I once hid and do not want hidden anymore. How can I go about unhiding all games entirely, acrosss the board? I've searched all over the website but there doesn't appear to be any controls for this and now Resident Evil 7 is sitting in limbo and I can't properly manage it to install it directly to my external drive. (I can only install it from the store, directly to my internal, and it's giving me the "Game Pass" version, despite everything saying I own it)

Before anyone asks/sugguests. I've restarted and "full shutdown" several times, to no avail. I've refreshed my games and apps and home, again several times to no avail.

My biggest concern at this point is that there are other games I've hidden that I can't find. Some of which may be in the same boat as Resident Evil 7 and I ended up outright buying but can't access.

Could really use some help, 'cause I'm about to pull my hair out on this one...
