Node.js facebook webbot

I have a node dev server linked to a test developement facebook messenger app. I have a list of offices with opening days and times, you need to create a test database from a form on line, write to Node.js the queries to read the Mysql database and submit it all through chatbot messenger. The test environment is a ubuntu server, with node.js and pm2 installed, which through https responds to messenger users. I need to add features to a bot messenger, written in nodejs, First you must be able to log in and log out through the APIs available on facebook. Unregistered users must be able to register with email and sms with the mobile number. Secondly, he has to book appointments for offices. The appointments are booked by reading from a myslq database, the availability. You must be able to book up to 1 month from the day you start the conversation. Some features are sketched in the project already run and linked to [login to view URL], but it would be best to do everything via buttons and postback, impeding the user to write on the chat.
