RNFirebase v6 Push Notifications are not coming both iOS&Android - firebase

Question

I am trying to send notifications from firebase console to my react-native app
I followed the poor documentation here as much as I understand: https://invertase.io/oss/react-native-firebase/v6/messaging/quick-start
I installed #react-native-firebase/app and /messaging and here is my code in component:
componentDidMount() {
this.reqNotifications()
this.checkNotificationPermission()
}
reqNotifications() {
requestNotifications(['alert', 'badge', 'sound']).then(({status, settings}) => {
console.log('NOTIFICATION STATUS' + status)
});
}
async checkNotificationPermission() {
const enabled = await messaging().hasPermission();
if (enabled) {
console.log('APPROVED');
await messaging().registerForRemoteNotifications()
messaging().getToken().then(token => console.log('token: >> ' + token))
} else {
console.log('NOT APPROVED');
}
}
I am requesting permission via react-native-permissions and permission request is
working.
My Apple APNs are OK on Apple and Firebase console
And I am getting my token by getToken() method on the code
succesfully.
But I cant send anything to device from firebase; nothing happening on neither foreground nor background . I tried with-token test and also tried normal but no, nothing happens.
I added this code to componentDidMount:
messaging().onMessage(async remoteMessage => {
console.log('FCM Message Data:', remoteMessage.data);
});
As I understand this subscribes for cloud messages and when I send some cloud message notification from firebase-console, I should get console output; but nothing happens.
I dont know what am I missing but I think there is a big update on this package and most of docs are for previous version and I really stuck here thanks for assist

for rnfirebase.io V6
componentDidMount = async () => {
this.checkNotificationPermission();
await messaging().requestPermission({provisional: true});
await messaging().registerDeviceForRemoteMessages();
await this.getFCMToken();
if (Platform.OS === 'android') {
this.createAndroidNotificationChannel();
}
this.backgroundState();
this.foregroundState();
};
checkNotificationPermission = () => {
firebase
.messaging()
.hasPermission()
.then(enabled => {
if (!enabled) {
this.promptForNotificationPermission();
}
});
};
promptForNotificationPermission = () => {
firebase
.messaging()
.requestPermission({provisional: true})
.then(() => {
console.log('Permission granted.');
})
.catch(() => {
console.log('Permission rejected.');
});
};
createAndroidNotificationChannel() {
const channel = new firebase.notifications.Android.Channel(
'channelId',
'Push Notification',
firebase.notifications.Android.Importance.Max,
).setDescription('Turn on to receive push notification');
firebase.notifications().android.createChannel(channel);
}
foregroundState = () => {
const unsubscribe = messaging().onMessage(async notification => {
console.log('Message handled in the foregroundState!', notification);
});
return unsubscribe;
};
// Register background handler
backgroundState = () => {
messaging().setBackgroundMessageHandler(async notification => {
console.log('Message handled in the background!', notification);
});
};
