How to allow Photos for an application?

So I’ve been trying to allow my photos for apps for the past 30 minutes. Whenever I click on the app in Settings, there is no option to allow photos. I’ve also already checked my Screen Time and Privacy and both of those are so I should be able to allow photos. However, it still won’t let me allow them. (iPhone 12 btw)
