Cannot get Notification content if app is in background

I can recevie the notification from firebase remotly. If the app is runing in foreground, I receive the notification content normally, but if the app is in background, I receive the notification and when click on notification, the app opens up, but the method: onNotification is not called for some reason. I have seen a lot of issues based on this problem, but no success.

here is my AndroidManifest.xml

`<application android:name=".MainApplication" android:label="@string/app_name" android:icon="@mipmap/icon" android:allowBackup="false" android:theme="@style/AppTheme">

    <meta-data android:name="com.google.firebase.messaging.default_notification_icon" android:resource="@mipmap/icon"/>

    <receiver android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationPublisher" />
    <receiver android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationBootEventReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>
    <service android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationRegistrationService"/>

    <service
        android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationListenerService"
        android:exported="false" >
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>


  <activity
    android:name=".SplashActivity"
    android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
  </activity>


  <activity
    android:name=".MainActivity"
    android:theme="@style/SplashTheme"
    android:label="@string/app_name"
    android:launchMode="singleTop"
    android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
    android:windowSoftInputMode="adjustResize"
    android:exported="true">
  </activity>
  <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
</application>`

and here is my App.js

import PushNotification from 'react-native-push-notification';

    class App extends Component {
      state = { color: 'red' };
      constructor() {
        super();
        PushNotification.configure({
          onRegister: ({ token }) => this.register(token),
          onNotification: notif => this.receivePushNotification(notif),
          senderID: 'XXXX',
          requestPermissions: true
        });
     }

        componentDidMount = () => {
          SplashScreen.hide();
          AppState.addEventListener('change', this.handleAppStateChange);
        };

        handleAppStateChange = appState => {
          if (appState === 'active') {
            PushNotification.popInitialNotification(notification => {
              console.warn('notification', notification); //notification is null
            });
          }
        };

        register = token => {
          console.warn('token', token);
        };

        receivePushNotification = notification => {
          console.warn('notification', notification); //only enter here if I receive the notification in foreground mode, if I receive in background and click on notification, this method is not being called
        };
    }

If anybody knows how to solve this, or know if FCM is supported by this library I would greatly appreciate it.
