How do I add myself to the Photo Shuffle feature on iPhone Lock Screen?

Hello,

I really enjoy the Photo Shuffle feature on the lock screen, but I’ve been having trouble adding myself (the iPhone owner) to it. When I go to the People tab, I see faces of others available for selection, but not my own.

I’ve tried several troubleshooting steps, including:

Removing and re-adding my contact information
Removing myself from the People tag
Renaming and editing my details

Unfortunately, none of these have worked, and I still can’t select my own face.

Could you please help me resolve this issue?
