Unable to get watches for newly created page through REST API

Question

I have a user A who is subscribed to wach all the content in the space.

But whenever new page has been added (by some another user B)  to the space I cannot find the user A in the list of wachers of the page using Confluence Cloud REST API call:
GET /wiki/rest/api/content/{id}/notification/child-created

When you navigate to the newly created page under user page A, you will find user A waching the page.
Is this an API issue? How can I get the waches of the page for new pages?

I found solution to my case. I need to use another endpoint to get watchers for the space: GET /wiki/rest/api/content/{id}/notification/created

So to get ALL watchers of the page a need to call
GET /wiki/rest/api/content/{id}/notification/child-created
and
GET /wiki/rest/api/content/{id}/notification/created
