Hi Ricardo,
I noticed that your chatbot developed in Botpress is facing an issue while integrating with the Messenger channel. It seems that the API is not enabled correctly, even though the webhook is working fine. The bot only receives messages when the administrator user of the page writes, resembling a development mode rather than the intended production mode. Meta has informed you that advanced Messenger permissions are not required for integration but has not provided a solution.
As a Messenger API specialist, I can help you enable the integration correctly. I have extensive experience in working with APIs and have successfully resolved similar issues in the past. I am confident that I can resolve this issue for you.
I am available to discuss the details via Zoom. Please let me know if you would like to proceed further.
Best Regards,
Muhammad
