For integration of facebook messenger on the facebook page with rocket.chat Livechat I followed the steps described here https://rocket.chat/docs/administrator-guides/livechat/omnichannel-integration/
There is one page which i can’t integrate and which is not visible on the list in the settings of Livechat/Facebook Messenger - even reload doesn’t help.
Disable and enable again doesn’t solve this problem (still no page on the list)
Is there any way to reinitialise integration (with permission granting for fb app to the pages) or any place on facebook side
to install the rocket.chat app to the page and grant permisions: manage_pages, pages_show_list, pages_messaging
