Groove Agent 4 trial and the USB-eLicenser

I want to try Groove Agent 4 and accordingly will be downloading the Trial Version for Mac OS X ( macos high sierra 10.13.6 ).

However, prior to making my request there is a notification at the Groove Agent 4 that to use the trial version you need an additional USB-eLicenser.

I already have a Steinberg USB-eLicenser that have my purchased Steinberg’s software and some " trial " Steinberg’s software.

Do I really need to buy another USB-eLicenser or do I just add the trial authorization code for Groove Agent 4 to that USB-eLicenser i already own./use ?

Please help because I am more then confused here.
