facebook - Send to Messenger button not showing -

-

i trying use send messenger plugin not rendered if try initialize fb user's page id , messenger app id. user has given me permission manage pages obtain page id 1 of them (he chooses which). there nothing in messenger docs scenario..

here how it:

flow:

  1. the user logs in using facebook login facebook sdk. gives me manage_pages permission.
  2. i fetch pages fb.api('/me/accounts') , display them user
  3. user selects 1 of these pages
  4. i create send messenger plugin element selected page id , app id, call fb.xfbml.parse() render plugin. not work if page not connected app seems.

my messenger bot not published (still in development).

things tried no results: - tried test users created in app - tried giving user tester role in app's settings

code:

<html> <body>     <script>         // if user logged in fb pages         function statuschangecallback(response) {             if (response.status === 'connected') {                 fetchpages();             }         }          // login listener         function checkloginstate() {             fb.getloginstatus(function(response) {                 statuschangecallback(response);             });         }          // initialize fb         window.fbasyncinit = function() {             fb.init({                 appid: 'xxxx',                 cookie: true,                 xfbml: true,                 version: 'v2.6'             });              fb.getloginstatus(function(response) {                 statuschangecallback(response);             });         };          // load sdk asynchronously         (function(d, s, id) {             var js, fjs = d.getelementsbytagname(s)[0];             if (d.getelementbyid(id))                 return;             js = d.createelement(s);             js.id = id;             js.src = "//connect.facebook.net/en_us/sdk.js";             fjs.parentnode.insertbefore(js, fjs);         }(document, 'script', 'facebook-jssdk'));          function fetchpages() {             fb.api('/me/accounts', function(response) {                  if (response && response.data && !response.error) {                      // pages managed logged in user                     var pages = response.data;                     var pageids = [];                     pagelist.innerhtml = '';                      // user selects 1 of these pages, let's first 1                     var selectedpage = pages[0];                      var pageselector = document.getelementbyid('pageselector');                     pageselector.addeventlistener("click", function() {                          // create send messenger element                         // messenger_app_id: app's id                         // page_id: id of selected page                         var sendtomessengerwrapper = document.getelementbyid('sendtomessengerwrapper');                         sendtomessengerwrapper.innerhtml = '';                          var plugin = document.createelement('div');                         plugin.setattribute('class', 'fb-send-to-messenger');                         plugin.setattribute('messenger_app_id', 'xxxx');                         plugin.setattribute('page_id', selectedpage.id);                         plugin.setattribute('data-ref', 'ref');                         plugin.setattribute('color', 'blue');                         plugin.setattribute('size', 'standard');                         sendtomessengerwrapper.appendchild(plugin);                          // re-render button - worked page directly connected app.                          fb.xfbml.parse(document.getelementbyid('sendtomessengerwrapper'));                     });                 }             });         }     </script>      <!-- notice permissions requesting -->     <fb:login-button id="loginbtn" scope="manage_pages,pages_messaging,pages_messaging_phone_number" onlogin="checkloginstate();">     </fb:login-button>      <input type="button" id="pageselector" value="connect page"/>      <!-- plugin button should rendered inside element -->     <div id="sendtomessengerwrapper"></div>    </body>

the issue webhook of app not subscribed page. if subscription had not been made through app settings of messenger product, or through graph api button not appear.
