Hello. I'm creating a fully immersive application and I need to use hand tracking. I've included the corresponding key (SHandsTrackingUsageDescription) in the info.plist. Everything works correctly. At the beginning, the application displays the corresponding permission. But now here's the question: if I make a mistake and you click on Don't Allow, the permission prompt won't appear again and the application stops working. How can I request permission again? Thanks.

Hello. I am developing a space painting application in C++ and Metal in Apple Vision Pro. It's essentially a port of the application called CoolPainrtrVR from PS4. I would like to implement an eye-tracking system for its menu system (3D menus displayed within the scene). How do I need to handle the necessary permissions to use eye tracking for the menu system? Thank you very much.
