```
 abstract Unit onWillDisplay(INotificationWillDisplayEvent event)
```
    Called when a notification is to be displayed to the user. This callback gives the implementor the ability to prevent the notification from displaying to the user.
    Note: If a Notification Service Extension INotificationServiceExtension exists, onWillDisplay will run after the extension is called, which has the following differences:
    The INotificationServiceExtension is configured within your AndroidManifest.xml.
    The INotificationServiceExtension will be called regardless of the state of your app, while willDisplay is only called when your app is in focus.
    The INotificationServiceExtension can make changes to the notification, while willDisplay can only indicate not to show it.
    Parameters:
    
    event - The notification will display event information.
