I have an application that only uses Webhook Subscriptions. I would like to move it from the sandbox to production, but it fails the graduation requirements for "5+ API calls per each used endpoint" and "Exercise all requested permissions." My application works fine. I've run it many times, my webhook is always invoked, and I take action on the JSON it sends me. However, I continually see "Your app hasn't made any API calls in the Sandbox yet" and "Webhook Subscriptions" always shows the red checkmark status. I am not sure what I need to do before my application activity is reflected in the graduation requirements. My client ID is: 51l0iRnoQ-a0qA1RoMOPYA
