facebook api get live comment

问题

as facebook mentioned here for get live comment

and i do like what they said

var source = new EventSource("https://streaming-graph.facebook.com/2025853151054872/live_comments?access_token=MY TOKEN HERE&fields=from{name,id},message");
source.onmessage = function(event) {
console.log(event);
  // Do something with event.message for example
};

this will give me 401 error and as they mentioned here at the end of page its mean

Unauthorized

Make sure your app has the right permissions and that the access token is valid.

so i checked my access token here

and its give me this result

 Metadata   {"sso":"chrome_custom_tab","auth_type":"rerequest"}
 Valid  True
 Data Access Expires    1560876206 (in about 3 months)
 Origin Mobile Web Faceweb
 Scopes email, publish_video, manage_pages, pages_show_list, publish_pages, public_profile

i don't know why there is error and every thing its right

also i test same url with android library library and same its give me error

user_videos permission but they doesn't mentioned that
