Missing Extension

I have recently purchased adobe Illustrator creative cloud suite (CC 2018).

I bought a “Roland Cutter GS24)“ and am able to utilise it through a plug-in called CutStudio for Illustrator.

I have downloaded the plug in, I have checked that it is sitting in the “my apps“ section on my creative cloud app however it doesn’t appear in the stream of actions.

when I open adobe illustartor the only option I have under window is find extensions through exchange and then it just goes to the place where I downloaded the plugin.

i have gone through the whole troubleshooting page and no luck...can anyone shed any light? I am completely new to all this and it’s doing my head in already!!! Help please!!!
