I found this tutorial for Watson Dialog. I would like to know how to use it in Watson Conversation. I want to implement only the part of the messenger structure, for my Watson enivar imagen, buttons.

In my bot I'm following this tutorial:

http://www.ibm.com/developerworks/br/cloud/library/criando-chat-bots-ibm-watson-pt2/index.html

https://github.com/nheidloff/facebook-watson-bot/blob/master/app.js

I want to put the app.js function on my bot; how do I indicate it in my bot's dialog watson conversation? I want to send pictures, videos, and buttons.

 function sendButtonMessage(recipient, text, buttons) {
   request({
     url: 'https://graph.facebook.com/v2.6/me/messages',
     qs: {access_token:token},
     method: 'POST',
     json: {
       recipient: {id:recipient},
       message: {
         "attachment":{
           "type":"template",
           "payload":{
             "template_type":"button",
             "text":text,
             "buttons": buttons
           }
         }
       }
     }
   }, 
   function(error, response, body) {
     if (error) {
       console.log('Error sending message: ', error);
     } else if (response.body.error) {
       console.log('Error: ', response.body.error);
     }
   });
 }
 
 function sendGenericTemplateMessageWithTweets(recipient, author, imageUrl, title, url) {
   request({
     url: 'https://graph.facebook.com/v2.6/me/messages',
     qs: {access_token:token},
     method: 'POST',
     json: {
       recipient: {id:recipient},
       message: {
         "attachment":{
           "type":"template",
           "payload":{
             "template_type":"generic",
             "elements": [
               {
                 "title":author,
                 "image_url":imageUrl,
                 "subtitle":title,
                 "buttons":[
                   {
                     "type":"web_url",
                     "url":url,
                     "title":"View Tweet"
                   }           
                 ]
               }
             ]
           }
         }
       }         
     }
   }, 
   function(error, response, body) {
     if (error) {
       console.log('Error sending message: ', error);
     } else if (response.body.error) {
       console.log('Error: ', response.body.error);
     }
   });
 }
