Provide example of how to get extra data from notification

[tobiasharle]

Please provide an example in NotificationDelegationService of how to access data that was set in the original web push message data property using showNotification

I can't see that any data can be found in the notification extras that is sent to the method onNotifyNotificationWithChannel

Hey,

Sorry for the delay. Currently the only way to pass information from JS notifications to the DelegationService is to encode it in the notification tag or id.
