On Wordpress, Woocommerce, and AffiliateWP, modify the email-order-details.php to have the name of the affiliate in the email template

I am pretty new to Wordpress and Woocommerce and I am want to know how to customize the woocommerce/templates/emails/email-order-details.php file to add the name of the Affiliate into the default email template so that i can see who is the affiate just by checking the notification email. I am using AffiliateWP to manage affiliates. If someone can help, I will be gratefull. Here is the original source code :

<?php
/**
 * Order details table shown in emails.
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/emails/email-order-details.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 3.7.0

With $order->get_billing_first_name() you can get the first name.

And with $order->get_billing_last_name() you get last name.

Sou you can try adding this

<div>Hello, <?php echo $order->get_billing_first_name();>? <?php echo $order->get_billing_last_name(); ?> </div>
