Handling push notifications when app is in the background

[estebanInnventto]

I'm trying to use push notifications with custom sound and vibration in a project. My problem is when the app is in the foreground, everything works fine but in the background I can't get the vibration to work.

I'm following the instructions I found here but it doesn't work for me.

index.js

import { AppRegistry } from 'react-native';
import App from './App';
import bgMessaging from './src/config/bgMessaging';
import { name as appName } from './app.json';

AppRegistry.registerHeadlessTask('RNFirebaseBackgroundMessage', () => bgMessaging);
AppRegistry.registerComponent(appName, () => App);

bgMeessaging.js

import firebase from 'react-native-firebase';
import Sound from 'react-native-sound';

export default async (message) => {
  try {
    const notification = new firebase.notifications.Notification()
      .android.setChannelId('insider')
      .android.setPriority(firebase.notifications.Android.Priority.Max)
      .setNotificationId(message.messageId)
      .android.setVibrate([1000, 1000, 1000])
      .android.setDefaults([firebase.notifications.Android.Defaults.Vibrate])
      .setTitle('My title')
      .setBody('My Body.');

    const notificationSound = new Sound('notif.mp3', Sound.MAIN_BUNDLE, (error) => {
      if (error) {
        console.log('failed to load the sound', error);
        return;
      }
      notificationSound.play((success) => {
        if (success) {
          console.log('successfully finished playing');
        } else {
          console.log('playback failed due to audio decoding errors');
        }
      });
    });

    return firebase.notifications().displayNotification(notification);
  } catch (error) {
    return Promise.resolve();
  }

I've also tried using Vibration.vibrate() but it doesn't work either

This is the library I'm using to handle notifications "react-native-firebase": "~5.5.5"

I've been stuck in this for a while and I would really appreciate any help I can get, I'm also fairly new to react native.
