title: FCM notification "click_action" not working
body: <p>I'm using a Cloud Function and sending push notifications with it. Sending notification works as expected but click_action attribute not working. When I click the notification nothing happens. Here is my code:</p>
  <p><strong>My notification payload:</strong></p>
  <pre><code>const payload = {
    notification: {
        title: 'Soru Çözüm',
        body: 'Attığınz soruya bir yorum geldi: ' + data.content,
        icon: 'ic_stat_logo',
        click_action: '.activities.SoruDetayActivity'
    },
    data: {
        title: 'Soru Çözüm',
        content: 'Sorunuz çözüldü.',
        post: data.parent
    }
  };
  </code></pre>
  <p><strong>Intent Filter:</strong></p>
  <pre><code>&lt;activity
      android:name=&quot;.activities.SoruDetayActivity&quot;
      android:label=&quot;Soru&quot;
      android:windowSoftInputMode=&quot;adjustResize&quot;&gt;
      &lt;intent-filter&gt;
          &lt;action android:name=&quot;android.intent.action.VIEW&quot; /&gt;
          &lt;action android:name=&quot;.activities.SoruDetayActivity&quot;/&gt;
  
          &lt;category android:name=&quot;android.intent.category.DEFAULT&quot; /&gt;
          &lt;category android:name=&quot;android.intent.category.BROWSABLE&quot; /&gt;
  
          &lt;data
              android:host=&quot;www.website.com&quot;
              android:scheme=&quot;https&quot; /&gt;
      &lt;/intent-filter&gt;
  &lt;/activity&gt;
  </code></pre>
