When I first add a cube, it looks black.

It'll look something like

import { PhysicalSpotLight } from "three-gpu-pathtracer";
extend({ PhysicalSpotLight });

<physicalSpotLight [...] />

If you're using TypeScript, you'll have more problems, because 1) three-gpu-pathtracer doesn't have types yet and 2) you have to extend JSX IntrinsicElements anyways. So your code will look something like:

import { PhysicalSpotLight as PathTracerPhysicalSpotLight } from "three-gpu-pathtracer";

class PhysicalSpotLight extends PathTracerPhysicalSpotLight {}
extend({ PhysicalSpotLight });

declare module '@react-three/fiber' {
  interface ThreeElements {
    physicalSpotLight: Object3DNode<PhysicalSpotLight, typeof PhysicalSpotLight>
  }
}
