Our App is trying to support Siri suggestion by donating user's activity. And I follow the document to ask for user‘s authorization. https://developer.apple.com/documentation/sirikit/intent_handling_infrastructure/requesting_authorization_to_use_siri
In iOS15.5, the alert did prompt as expected; but in iOS 15.4, the alert did not prompt, and the authorization result is default authorized; in iOS 15.0，the alert did not prompt and the authorization result is default denied.
I have two questions： 1、using requestSiriAuthorization, and the alert doesn't prompt, does it fit the expectation, or it's a system bug？ 2、when our app only uses MediaIntent, do we need ask for Siri authorization？
