Steam – Import Data into Custom Fields

Good Evening,

I added a custom field to my users page by editing my functions.php.

function modify_contact_methods($profile_fields) {
        //Add New Fields
        $profile_fields['steamid'] = 'Steam ID';

        return $profile_fields;
}
add_filter('user_contactmethods', 'modify_contact_methods');

I need to add the SteamID using the Steam Authentication with your plugin to this field. I attempted to edit the Steam.php file Located in wordpress-social-login\hybridauth\Hybrid\Providers\Steam.php with the following line:
$userProfile['steamid' ] = property_exists( $data, 'steamid' ) ? $data->steamid : '';

However, this does not seem to add the SteamID to the custom field I created. How should I go about doing this?

The page I need help with: [log in to see the link]
