Unable to grant premission to enable camera on iOS

So I’m trying to test AR application on mobile but whenever I click grant access it says “Permission is needed” and returns me back to this page

It sounds like you’re facing a permissions squishmallows issue while trying to test an AR application on your mobile device. Double-check your app’s permissions settings and ensure that it has the necessary access to use AR features. If the problem persists, you might want to reach out to the app’s support for assistance.
