Assigning First and Last Name from registration from to User Profile

Hello,

I use this sample code to add a first name field to the field group and assign it to the user type.

    $meta_boxes[] = [
        'title'  => __( 'User Meta', 'your-text-domain' ),
        'id'     => 'user-meta',
        'type'   => 'user',
        'fields' => [
            [
                'name' => __( 'First Name', 'your-text-domain' ),
                'id'   => $prefix . 'first_name',
                'type' => 'text',
            ],
        ],
    ];

and use this shortcode to display a registration form
[mb_user_profile_register password_strength='false' id="user-meta"  show_if_user_can="manage_options"]
`

the value of the first name field displays as well in the admin area after creating a user. Can you please export your field group to a JSON file and share it here? I will take a look.
