how to ask permission popup multiple reveal? (notification, att)

Question

I want to reveal att permission popup after notification permission popup interactions

I try to write it to be handled in the completionHandler closure after calling the requestAuthorization method, but it didn't work

[[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:UNAuthorizationOptionAlert | UNAuthorizationOptionSound completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if( @available(iOS 14.0, *) ) {
            if( ATTrackingManager.trackingAuthorizationStatus == ATTrackingManagerAuthorizationStatusNotDetermined ) {
                [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
        // do something
        }];
    }
}
