How to put in a "(App Name) would like you to allow Camera" or something like that into a SwiftUI view?

I already have the APIs and keys in, but how do I put in the permission popup on a SwiftUI view? I'd really love it if somebody could help, because the only thing I see is a documentation about the whole thing, but it's telling me where to put the code. Everywhere I put it, it just gives me an error.
