I am authorised with scope like this: business_management,email,public_profile,pages_manage_posts,publish_video,pages_read_engagement,pages_manage_posts But I always got error when I publish to my page: (#200) If posting to a group, requires app being installed in the group, and \ either publish_to_groups permission with user token, or both pages_read_engagement \ and pages_manage_posts permission with page token; If posting to a page, \ requires both pages_read_engagement and pages_manage_posts as an admin with \ sufficient administrative permission How to fix it?
