[Error] => (#200)

So I’ve gotten this error for posting to groups
Array ( [Warning] => [Error] => (#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 )

I have created a facebook app called AA Thursdays and this is listed in the app review
Approved: publish_to_groups, Groups API

I am not sure what else to do from there
