registration is not called

[uhotspot4]

I am using this plugin in capacitor.
I don't receive any registration event.
Here is how I call the init:

  const pushNotification = PushNotification.init({
	   ios: {
		alert: 'true',
		badge: 'true',
		sound: 'true'
	  }
  });

And here is the log I get:

Push Plugin VoIP missing or false
⚡️ [log] - Permissions statuses: authorized
⚡️ [log] - Successfully requested remote notifications authorization
Push Plugin register called
PushPlugin.register: setting badge to false
PushPlugin.register: clear badge is set to 0
PushPlugin.register: better button setup
FCM Sender ID (null)
Using APNS Notification

I would appreciate if someone can tell me what I am doing wrong!
