How to install Octopus in Rhino 8

Hello i have the Testing Version for 90 days of Rhino

I really would like to optimize with the Octopus Plugin but it wont show up.

i already installed plugins like anemone into the components folder.

but if i put the octopus gha and even the dll files into the components folder and restart rhino after it wont show up. Does it even work in Rhino 8 ? What am i doing wrong ?

Help would be really good.
