title: FCM Push notification is not opening the application
body: <p>I am receiving FCM Push notifications but the app is not opened while taping the notification that are delivered in the system tray while the application is in the background.</p>
  
  <p>My <strong>Payload</strong> from Back End looks like this:</p>
  
  <pre><code>Array(
      [registration_ids] =&gt; Array
          ([0] =&gt; some value)
  
      [priority] =&gt; high
      [notification] =&gt; Array
          (
              [body] =&gt; Booking Cancelled: Your recent Booking attempt for Sound mix was declined.
              [title] =&gt; Booking Rejected
              [click_action] =&gt; USER_BOOKING_REJECTED
              [sound] =&gt; default
          )
  
      [data] =&gt; Array
          (
              [type] =&gt; USER_BOOKING_REJECTED
              [booking_id] =&gt; 331
          )
  )
  </code></pre>
  
  <p>I added this <strong>USER_BOOKING_REJECTED</strong> as action in Manifest for the concerned Activity.</p>
  
  <p>Like this:</p>
  
  <pre><code> &lt;activity

  <p>Even though I get the notification in the system tray, the app is not opened while taping the notification. Any Help?</p>
