Help to unhide or just open hidden APP's on IOs 18.3.1?

Hi

I've tried to hide some APP's for Fun, and to find out how it works.

Hiding APP's is easy, but to recover them is impossible?

So how to unlock a hidden app, when after FaceID (in menu hidden Apps) I can see all hidden apps but pressing logo for long dosen't do anything?

I've tried for up to 5 minutes. Either i can only press the name of the app, and then i end up i the APP settings or if i press the logo of the APP, nothing happens?

I can only go into app setting of the single app that i've hidden?

Update to 18.3.1 didn't help?

I've now go several App i cannot use and don't know how to get back again?

Pls help
