Capture FB users location, phone

Hello,

I want to capture the person’s location and phone number from their FB profile and store it, but can’t figure out how.

I saw this similar thread https://www.ads-software.com/support/topic/feature-request-get-user-birthday-and-location but didn’t understand the code much. There is no function.php file in the plugin.

Please can anybody help with some code and where to add it. Thank you.
