Buying Davinci Resolve Studio for Linux

I am very happy that 15 now has native linux audio support. Thank you for that. Thats why i am looking into buying resolve studio for my linux workstation. Here is my question about the licensing/dongles because i am not sure about that.
If i buy a dongle for davinci 14 then it will work ony mac/linux and windows?
I read something about activation codes and dongles. When do i need a dongle and when is an activation code neccessary?
That is important because i got an offer buying a davinci dongle that was bundled with a camera and my mate has 2 licenses. As far as i know i can not generate/get an activation code if i would by the dongle from him.
Thank you for you help.
