 The tracking status can return one of the following values:
 
-* `'unavailable'`: The tracking API is not available on the current device. That's the case on Android devices and iPhones below iOS 14.
-* `'denied'`: The user has explicitly denied permission to track. You'd want to respect that and disable [advertiser ID collection](#setAdvertiserIDCollectionEnabled).
-* `'authorized'`: The user has granted permission to track. You can now enable [advertiser ID collection](#setAdvertiserIDCollectionEnabled).
-* `'restricted'`: The tracking permission alert cannot be shown, because the device is restricted. See [`ATTrackingManager.AuthorizationStatus.restricted`](https://developer.apple.com/documentation/apptrackingtransparency/attrackingmanager/authorizationstatus/restricted) for more information.
-* `'not-determined'`: The user has not been asked to grant tracking permissions yet. Call `requestTrackingPermission()`.
