I have created a personal account within the Kakao developer console and registered an app.
Our objective is to seamlessly receive messages from Kakao and send messages to Kakao within our software. After conducting some research, we understand that we need to switch our app to a BizzApp to achieve this functionality. We kindly request your assistance in switching our app to a BizzApp without Korean registration number. It would greatly benefit us if you could provide documentation on how to implement the send and receive flow for Kakao, including instructions on setting up the webhook URL.

Please refer to the following document for a more detailed introduction to the Messaging API
