Facebook repproved the permission pages_manages_posts

Hi there,

We’d like to use plugin in order to re-post our posts on social media.
We’re following the documentation to set up the social networks, but the Facebook Team repproved the permission pages_manage_posts and approved the rest (pages_show_list, pages_read_engagement, publish_to_groups, API de grupos).
They ask to us to show the usage that permission but we don’t know why it is needed and how to demonstrate to them.
Will be do you tell us about providing any hint to this case?

Thanks a lot
