How to get the permission alert click event in (.plist) privacy usage description?

In the plist setting "Privacy - Camera Usage Description", it shows a permission alert to allow or deny usage of the camera.

How can I get the alert's accept or refuse button event to do something? Here is my .plist file snapshot:

Request camera permission using

AVCaptureDevice.requestAccess(for: AVMediaType.video) { granted in }

and you'll get the user's response in the granted parameter of the closure.
