Not using integrated graphics at all

I have installed optimus-manager and tried to set it up with hybrid graphics like I used to on Manjaro, but it seems nothing is even touching integrated graphics. I don’t want my desktop and apps like discord using my dedicated card while I’m gaming, but so far everything just uses the dedicated graphics!
Where should I start in troubleshooting this?
I have a dedicated GTX 1650, and integrated AMD Cezanne graphics.
