Unable to delete app from my home screen on my iPhone XR

Just recently I noticed when I try to delete an app from my homescreen, instead of giving me the option to delete it, it just says I can move it to the app library. When I go to the app library and click the app, there is no option to delete either. I have already made sure that my Screen Time settings allow me to delete apps. What else can I do?
