title: PWA register push notifications for Azure Notification Hub using JS only
body: <p>I am creating a PWA and following the example for subscribing to push notifications as detailed in this Google Lab - <a href="https://developers.google.com/web/fundamentals/codelabs/push-notifications/" rel="nofollow noreferrer">Adding Push Notifications to a Web App</a></p>
  
  <p>The example uses Firebase Cloud Messaging (FCM) but we already have an Azure Notification Hub</p>
  
  <p>Am I able to register with ANH using the same approach (JS only) - would it be a case of sending an API call with a payload containing the hub name, connection string and registration id?</p>
