Corsair Lightning Node configuration problem

When I started the program first time it detected some device "Corsair Lightning Node" with 2 channels and asked me how many LED's are there. As I had no clue that I even had some "Corsair Lightning Node" existing in the computer (in hindsight, it is Corsair iQue T220 RGB chassis... probably somehow connected to motherboard? I mean how else could I control chassis leds from OpenRGB?) and to get rid of the popup, I selected 1 for both. Now later I found out to which LED's this indicates (channel 1 apparently is chassis front fan(s?); channel 2 doesn't seem to change anything), but the problem is that I can now control only 1 led out of many on only 1 fan out of 3 fans and nowhere to change the number of LEDS the Node channel should have.

So where can I reset or change the number of LEDS controlled by the Corsair Node per channel? Did I mislooked or this functionality doesn't exist?
