How to work Facebook Messenger bot generic template sharable

Question

What happens to the actual messenger in the sharable feature?

I can not understand the change in the native share button (both PC and mobile).

I would like to know what the sharable setting changes.

There is no change in setting values (see image).

Sample request:

 {
  "recipient":{
    "id":"<PSID>"
  },
  "message":{
    "attachment":{
      "type":"template",
      "payload":{
        "template_type":"generic",
        ***"sharable":true or false,***
        "elements":[
           {
            "title":"Welcome to Peter\'s Hats",
            "image_url":"https://petersfancybrownhats.com/company_image.png",
            "subtitle":"We\'ve got the right hat for everyone.",
            "buttons":[
              {
                "type":"web_url",
                "url":"https://petersfancybrownhats.com",
                "title":"View Website"
              },{
                "type":"postback",
                "title":"Start Chatting",
                "payload":"DEVELOPER_DEFINED_PAYLOAD"
              }              
            ]      
          }
        ]
      }
    }
  }
}

Answer 1

self solved.

If the button type of the element button is postback or share, sharable does not work.
