title: React native - How to navigate on Push notification click?
body: <p>I am using react-native-push-notification.
  I had the issue of notifications not being displayed when the app is in background/killed state, to which the solution in multiple forums and GitHub is that we initialize and configure push notification (PushNotification.configure()) in index.js
  Inside the PushNotification.configure() function, onNotification() is the function called when the Push Notification is clicked. On click, I want to navigate to a particular screen in the app, but that is not possible currently as there is no navigation prop available in index.js</p>
  <p>Is there any way the navigation could be made possible ?</p>
