Add product description (content) to WooCommerce customer processing order email

Hi Woo experts,
I’m looking for a way to add the product description (content) to the WooCommerce customer processing order email as it contains important information to pass to the customer that they need for their records.

I presume I need to edit the template at WooCommerce > Settings > Emails > Processing Order, but what line and what with?

Does anyone have any cut and paste code?

Thanks!
