How to single configure your keyboards light for Razerblade 15 2020

Hej Razer Ive recently just bought your gaming laptop. Razer blade 15.6 2020 I dont use your plug-in keyboards, i use the one on the laptop. So i wanted to configure my gaming layout. for 2 days ive not come to how i can " mark " buttons "qweasdr " with red. it seems to me, i can only mark the entire keyboard. ive watched many youtube videos, for the plug-in keyboards useless for me. ive reinstalled the apps a few times. I have the synapse 3.0 for my laptop and the synapse 2.0 for my mouse and headset. i can see the keyboard layout, but im not allowed to single pick which should be turned on and off. i see in your tutorials it is possible. Why cant i just do it? Also my laptop is not detected in synapse 2.0 Please help me.
