Change the email template

Hello,
I am using virtuemart as a catalog and inventory manager. There are a lot of functions such as pricing and billing that I do not use and I changed the component to suit my needs and it works pretty well.
However, regarding the mailing, I would like to change the message by removing all regarding billing, pricing, and keep only the products ordered.
I think it is in the folder / components / com_virtuemart / views / invoice but could you confirm me and tell me what file I need to edit.
Thank you very much.
Philippe
