How to subscribe a FB page to a facebook app?

问题

I'm trying to subscribe a Facebook page to my facebook app. It's a messenger app where I need to subscribe the page to my webhook added in the app.

Using the graph API, I have the page access token and page id, I have tried the subscribed_apps API but it didn't work

 FB.api('/' + page.id+ '/subscribed_apps?access_token=' + 
         page.access_token,function (response) {
            console.log(response)
        });

Is there an API to make the page to subscribe to my webhook in the app.
