Display attribute in email issue

G’day

I need to add one attribute (pa_colorcode) to be visible in order emails for admin. How can I do so?

https://joxi.ru/YmEBxJgUwRbZD2

class for the attribute is
“woocommerce-product-attributes-item woocommerce-product-attributes-item–attribute_pa_colorcode”

That’s what I found online to make it work (sorry, I’m not a programmer so probably this code is rubbish)

for my functions.php

function echo_1($attribute_value){ echo $attribute_value[‘pa_colorcode’]; }
add_action(‘atr_colorcode’, ‘echo_1’);

for email-order-items.php
do_action(‘atr_colorcode’, array(‘color code:’) );

Apparently it is not showing me anything in my email after ordering an item.
Other solutions I’ve found online are not working for me neither.

Please help. Thank you in advance.
