  <p>Also to done in Info.plist FirebaseAppDelegateProxyEnabled = NO</p>
  
  <p>I don't know for now but I got the print(...) in didReceiveRemoteNotification but don't get the popup. I send the message from Firebase -> Console -> Notification -> Single device and copy here the token which I got from xCode Console -> func tokenRefreshNotificaiton</p>
  
  <p>Get the next in console, but don't get popup</p>
  
  <pre><code>&lt;FIRAnalytics/INFO&gt; Firebase Analytics enabled
  InstanceID token: TOKEN_ID
  Connected to FCM.
