We are facing one issue which is related to Facebook pages list not showing. Initially as explained we are using Facebook Messenger Integration and for this, the accounts Facebook pages worked properly for subscription and token renewal process for normal accounts which have no admin access or developer access on the app. But when we connect Facebook page to Instagram Professional account which is actually requirement of Facebook for implementation of Instagram chat then list of Facebook pages not showing to account. It is only showing to the admin account or the account having developer access. We required these pages access as we need to generate/update Facebook API tokens. We have the following permissions of advance access on our App.

Pages_messaging, Business Asset User Profile Access, Pages_manage_metadata , Public_profile ,Instagram_manage_messages Email,Pages_show_list, instagram_basic

Can you please guide us what we are missing and if any other permissions required please let us know. We are very anxiously waiting to implement Instagram chat with our system Thanks
