Can I target specific users instead of sending to everyone?

Yes! Use the `create_notification` tool and provide a list of `include_player_ids`. This ensures the notification is only delivered to the specific devices you've identified.

How can I check if a scheduled notification was actually sent?

You can use the `get_notification` tool with the Notification ID. It will return real-time delivery metrics, including the number of successful deliveries and current status.

Is it possible to manage multiple OneSignal apps?

Yes. While the core operations use the primary App ID provided in credentials, you can use `list_apps` (requires User Auth Key) to see all your applications and their respective IDs.
