How to hide "invoice" download button to users in their subscription history?

I want to hide the "invoice" download button to users in their subscriptions history page, order page and so on

in other words I want to be able to download their invoice from the admin panel, but the user must not be able to dowload or see it

if 2 different templates file where being used to generate the "sales list" in the admin panel and the "subscriptions history" list on the user end

then I could comment out some code in the template used for the user

but... it is so? or the same template file is being used for both views?

thank you
