How to change the role of the buyer of a certain product?

Question

WordPress

Good day!
There was a need to catch the moment of registration when paying through WooCommerce and set a specific role for the user, depending on the product that he bought.
Tell me the necessary hooks and how to implement it better, thanks in advance!

It turned out to change the role only in usersmeta, but also success

function s1_change_role( $order_id ) {

    $order = new WC_Order( $order_id );
    $items = $order->get_items();

    foreach ( $items as $item ) {
        $product_name = $item['name'];
        $product_id = $item['product_id'];
        $product_variation_id = $item['variation_id'];

        if ( $order->user_id > 0 && $product_id == '522' ) {
            update_user_meta( $order->user_id, 'paying_customer', 1 );
            $user = new WP_User( $order->user_id );

            // Remove role
            $user->remove_role( 'subscriber' ); 

            // Add role
            $user->add_role( 'Любитель' );
        }
        if ( $order->user_id > 0 && $product_id == '527' ) {
            update_user_meta( $order->user_id, 'paying_customer', 1 );
            $user = new WP_User( $order->user_id );

            // Remove role
            $user->remove_role( 'subscriber' ); 

            // Add role
            $user->add_role( 'Клиент' );
        }
        if ( $order->user_id > 0 && $product_id == '528' ) {
            update_user_meta( $order->user_id, 'paying_customer', 1 );
            $user = new WP_User( $order->user_id );

            // Remove role
            $user->remove_role( 'subscriber' ); 

            // Add role
            $user->add_role( 'VIP-Клиент' );
        }
    }
}

Everything is clear and simple, only the output is crooked, it seems to me, the main thing is that it works)

$current_user_id = get_current_user_id();
  $user_info = get_userdata($current_user_id);

  $massiv = $user_info->caps;
  foreach($massiv as $key => $value)
  {
    if($key == 'Любитель'){
      echo 'Роль пользователя: ';
      echo substr($key, 3);
    }
    if($key == 'Клиент'){
      echo 'Роль пользователя: ';
      echo substr($key, 3);
    }
    if($key == 'VIP-Клиент'){
      echo 'Роль пользователя: ';
      echo substr($key, 3);
    }
  }
