We're encountering an authorization issue when trying to retrieve post engagement data (shares and comments) for one of our customers. Our application has the pages_read_engagement permission, which should be sufficient, but the API still returns a "(#10)" error message.

The error message suggests we might need the 'pages_read_engagement' permission or the 'Page Public Content Access' feature. However, we've verified that the permission is already enabled for the specific page.
