Conditionally sync UM user role based on WP role (Gravity forms)

gistfile1.php

/* This code will sync the UM role based on WP role using gravity registration */
 
add_action("gform_user_registered", "um_gravity_user_role_sync", 200, 4);
function um_gravity_user_role_sync($user_id, $config, $entry, $user_pass) {
 
    $user = new WP_User( $user_id );
    $wp_role = $user->roles[0];
    
    // if WP role is subscriber, set UM role to member
    if ( $wp_role == 'subscriber' ) {
        update_user_meta($user_id, 'role', 'member');
    }
 
}

This synchronization start after an online user submit GF "registration form" or only after that user is created and activated (es. after the admin reviw and/or after user email link activation?

and more important question, this code is useful to evitate to manual set same wp role for ultimate member and gravity form registration?
