Hello,
So you will need a 10$ adapter to connect the Lian Li STRIMER plus to the Commander pro or Lightning Node (I tested on both and both works). (https://www.ebay.com/itm/372521827376)
Once it is done, press M1 on the Strimer Plus Controller for a couple seconds to activate Motherboard mode (it also works with Icue, not just motherboards RGB like AURA, etc).
Once all that is done, go to Icue and select the channel of the Strimer. You can configure it as RGB Strips or even fans. I've tested both and it works.
Enjoy
