Добавить собственный текст для определенного продукта в конкретное уведомление по электронной почте в Woocommerce

Я хочу добавить дополнительный текст «В этом конкретном элементе есть предложение и т. д.» Только для определенного продукта (Идентификатор продукта: 1) в customer-completed-order.php в WordPress. Другие продукты не нуждаются в этой дополнительной строке. Может ли кто-нибудь помочь мне узнать это?

 <?php
   /**
    * Customer completed order email
    *
    * This template can be overridden by copying it to yourtheme/woocommerce/emails/customer-completed-order.php.
    *
    * HOWEVER, on occasion WooCommerce will need to update template files and you
    * (the theme developer) will need to copy the new files to your theme to
    * maintain compatibility. We try to do this as little as possible, but it does
    * happen. When this occurs the version of the template file will be bumped and
    * the readme will list any important changes.
    *
    * @see https://docs.woocommerce.com/document/template-structure/
    * @package WooCommerce/Templates/Emails
    * @version 3.5.0
