So i got the app working fine for a personal page with a leadform gen, but I am unable to create an app for a business page to subscribe and pull the newest leads created via the graph api. It is only calling the app from the personal profile, so the ad account in the business account is not showing a webhook registered. How does one create an "APP" using the Facebook Business Manager and use the Graph API with a Business Facebook account? I don't see a way to create an app for a business page. I assigned the app to be managed by the business page as well as the ad account, but the lead gen from in our ad account is still not showing a webhook.
