自动将页面订阅到 messenger webhook

Question

I am working on a messenger platform that uses a messenger webhook to receive messages, and the Graph API to send messages. I currently need to go into my app settings and choose to subscribe pages that I already own.

I am wondering how I can subscribe pages that I don't own to my webhook. Is this possible if I have the Page Access Token? I can build an OAuth2 flow to get the Page Access Token, but I don't see what to do with it once I have it.

Any help is appreciated.

This can be achieved by making a POST call to /{page-id}/subscribed_apps endpoint with your Page Access Token.
