Can users generate their invoice on the frontend?

-- url of the page with the problem -- : shop.smartgart.com
-- HikaShop version -- : Business 2.6.4
-- Joomla version -- : 3.6.4
-- PHP version -- : 5.5.28
-- Browser(s) name and version -- : Chrome current
-- Error-message(debug-mod must be tuned on) -- : none

Hi support,

I have enabled the "my account" module and then can click "view your orders".
This lists me the previous orders, and when I click on a order number, I see the items bought,
however I do not have an "invoice" button like I have on the backend.

Does this functionality exist somewhere for a frontend user?

best regards

Klaus
