Not able to get user email id

[wdayanand]

I need email in my game for further communication like rewards, notification, etc
but as per document I didn't see any way to get email I tried with javascript sdk using
FB.login(function (response) {
if (response.authResponse) {
FB.api('/me?fields=email', function (userInfo) {
console.log(userInfo.email);
});
} else {
console.log('Auth cancelled.')
}
}, {
scope: 'email'
});

but i always got Blocked opening error ="in a new window because the request was made in a sandboxed frame whose 'allow-popups' permission is not set"

Please let me know How i can get user email id

Per discussion at the thread:
https://stackoverflow.com/questions/53494945/fetch-the-user-information-with-the-permission-into-facebook-instant-game
One must use the relevant FBInstant methods (e.g. FBInstant.player.getName()) to get player information. And it is currently not possible to access the player’s email address and gender from within Instant Games.

Let me know if you have further questions. Thanks.
