To add scope in request.

[amitrana4]

If we need page list and other info of user we need to pass a scope which add permission links in facebook auth page while login.

Solution :
We need to add more scope like below.

return new Promise(function (resolve, reject) {
FB.login(function (response) {
if (response.authResponse) {
var /** @type {?} */ accessToken_2 = FB.getAuthResponse()['accessToken'];
FB.api('/me?fields=name,email,picture', function (res) {
resolve(FacebookLoginProvider.drawUser(Object.assign({}, { token: accessToken_2 }, res)));
});
}
}, { scope: 'email,public_profile,manage_pages,pages_manage_instant_articles,pages_show_list,publish_pages,read_insights' });
});
