How to display custom attributes in the product tab to other attributes?

Question

WordPress

I brought the fields to the admin panel (code below), now I want to add them to the rest of the attributes

add_filter( 'woocommerce_product_data_tabs', 'add_my_custom_product_data_tab' );
function add_my_custom_product_data_tab( $product_data_tabs ) {
  $product_data_tabs['my-custom-tab'] = array(
    'label' => __( 'Доп.атрибуты', 'my_text_domain' ),
    'target' => 'my_custom_product_data',
  );
  return $product_data_tabs;
}

add_action( 'woocommerce_product_data_panels', 'add_my_custom_product_data_field' );

function add_my_custom_product_data_field() {
  global $woocommerce, $post;
  ?>
  
  <div id="my_custom_product_data" class="panel woocommerce_options_panel">
    <?php
  woocommerce_wp_textarea_input(
                        array(
                            'id'        => 'giftwrap_cost1',
                            'label'     => __( 'Текст', 'tpwcp' ),
                            'desc_tip'  => __( 'Введите текст', 'tpwcp' )
                        )
                    );
  	 woocommerce_wp_select(
                        array(
                            'id'        => 'giftwrap_cost2',
                            'label'     => __( 'Упаковка', 'tpwcp' ),
                             'options' => array(
                                              'value1' => __( 'Мешок', 'textdomain' ),
                                              'value2' => __( 'Text 2', 'textdomain' )
                                            )
                        )
                    );
    ?>
  </div>
  <?php
}

add_action( 'woocommerce_process_product_meta', 'wc_product_custom_fields_save' );

function wc_product_custom_fields_save($post_id) {
  
  $wc_custom_product_number_field1 = $_POST['giftwrap_cost1'];
    if (!empty($wc_custom_product_number_field1)){
        update_post_meta($post_id, 'giftwrap_cost1', esc_attr($wc_custom_product_number_field1));}
  
  	$wc_custom_product_number_field2 = $_POST['giftwrap_cost2'];
    if (!empty($wc_custom_product_number_field2)){
        update_post_meta($post_id, '_product_attributes', esc_attr($wc_custom_product_number_field2));}
  
 
  
  
}
