Custom meta field doesnt showing

I tried this code:

//invoice

add_action( 'wpo_wcpdf_after_item_meta', 'wpo_wcpdf_product_custom_field', 10, 3 );
function wpo_wcpdf_product_custom_field ( $template_type, $item, $order ) {
    // check if product exists first
    if (empty($item['product'])) return;
  
    // replace 'Location' with your custom field name!
    $field_name="order_jmeno_ucastnika1";
    $location = $item['product']->get_meta($field_name,true,'edit');
    if (!empty($location)) {
        echo '<div class="product-location">Location: '.$location.'</div>';
    }
}

Also this code:

add_action( 'wpo_wcpdf_after_order_data', 'wpo_wcpdf_my_custom_field', 10, 2 );
function wpo_wcpdf_my_custom_field ($template_type, $order) {
    if ($template_type == 'invoice') {
        ?>
        <tr class="order_jmeno_ucastnika1">
        <th>Custom Field:</th>
        <td><?php echo $order->get_meta('order_jmeno_ucastnika1'); ?></td>
        </tr>
        <?php
    }
}

But nothing showed. I have also PRO version of plugin. I need show this field in invoice with condition, when is in order virtual product.

It can be displayed under product in invoice, but also under billing informations.
