How to customize Woocommerce Gift Card Emails

Dear support, please advise how to customize gift card emails from the official woocommerce extension: https://woocommerce.com/de-de/products/gift-cards/

The extension introduces two new email types “gift card received” and “self use gift card received” how do I customize it using your plugin.

In “add new” I only see the template “self use gift card”.

I want to change the text/layout and need to translate for WPML.

Thanks in advance.
