title: Deliver a notification with vibration, LED light, sound using FCM
body: <p>I have implemented the sample Firebase code from <a href="https://github.com/firebase/functions-samples/tree/master/fcm-notifications" rel="nofollow noreferrer">here</a> to see if it works with my project.</p>
  
  <p>I receive a notification when my app is killed or closed once the database child value changes, all is good, but how do I set the vibration, sound and led light blinking function using code from <a href="https://github.com/firebase/functions-samples/blob/master/fcm-notifications/functions/index.js" rel="nofollow noreferrer">here</a>? Do I need to detect the notification with android or I have to implement it with the payload somehow?</p>
