title: web push notification is not appearing in chrome
body: <p>I have started implementing web push notification in a web application. </p>
  
  <p>Got Steps from <a href="https://developers.google.com/web/fundamentals/codelabs/push-notifications/#subscribe_the_user" rel="nofollow noreferrer">Google Post Here</a></p>
  
  <p>But the notifications don't appear in chrome browser. Also, I have used the code and integrated into my application and the notifications appear in Firefox but not in chrome.</p>
  
  <p>I doubt, in registered service worker, the <code>self.addeventlistener('push', option)</code> is not working properly in chrome.</p>
  
  <p>Any ideas </p>
