Handle user_ref field of sender in messaging_referrals

[swapnilpandey03]

I am receiving this payload from a chat plugin when a user presses the get started button:

{
   "object":"page",
   "entry":[
      {
         "id":"124924473551",
         "time":1622440770209,
         "messaging":[
            {
               "recipient":{
                  "id":"124924473551"
               },
               "timestamp":1622440770209,
               "sender":{
                  "user_ref":"105917555039643"
               },
               "postback":{
                  "payload":"hey",
                  "referral":{
                     "ref":null,
                     "source":"CUSTOMER_CHAT_PLUGIN",
                     "type":"OPEN_THREAD",
                     "referer_uri":"https:\/\/www.xyz.com\/abcd",
                     "is_guest_user":false
                  },
                  "title":""
               }
            }
         ]
      }
   ]
}

However, when I convert it into a MessageItem, there is no such field as user_ref in sender but only id. Am I missing something or is this field yet to be added?

RestFb version we are currently using: 3.0.0

According to Facebook: Link here
Breaking Change (May 5, 2020) Graph API v7.0+ messaging_referrals webhook event from the chat plugin will not be returning sender.id field. It will return a new sender.user_ref field. This changes will take effect on all older Graph API versions starting Nov 2, 2020.

Oh yes, this field is missing. I'll add it. Thanks for the json!
