Auth0 with Facebook user_link issue

I am facing an issue that Auth0 response is not returning the user_link information after checking the Profile URL checkbox on Authentication > Social > Facebook.

I also tried to debug the Social by creating a new rule and using the Real-time Webtask Logs to troubleshoot. However, I don’t see the response either.

May I know do I need to go to Facebook Developer and modify the permission under the Permissions and Features section?

Any help would be much appreciated.
