Answer 1

Since the version 10.0.0: onSelectNotification has been changed to onDidReceiveNotificationResponse as mentioned in the ChangeLog.md:

onDidReceiveNotificationResponse: invoked only when the app is running. This works for when a user has selected a notification or notification action. This replaces the onSelectNotification callback that existed before.
