I want to connect Facebook Messenger with Manychat, but there seems to be a problem with the connection.

If I go to the settings and click on “messenger - connect”, I see the correct page to connect (I also have the necessary permissions), but I cant connect it, I can only send a connection request for the page to another page admin. Why is that?

I also tried to reconnect the facebook page with manychat but as soon as I go to the connect-window for facebook messenger, the button says “request send” and “ Your request is pending XXXXXXX`s approval. They can easily access it in their Email inbox or under the account`s Settings → Team Members.”.

The request however was never send or received by the account in question, but I cant pull the request back or resend it.
