User Profile

Hello, I have only recently started developing extensively with Apple. When I first created my application, I let Xcode handle the Provisioning Profile, App ID, etc. Now, I see that I have to add Sign in with Apple functionality to be able to get my app onto the App Store. However, when I went to my Apple Developer account, my Xcode generated Provisioning Profile and App ID were no where to be found. I tried to contact Apple Developer Program Support for help, but they only pointed me towards their documentation, where I could not find any help. Could any one explain to me how this works, and why my Xcode generated Provisioning Profile and App ID are not in my developer account?? Any help would be greatly appreciated.
