Unable to request adapter for webgpu on WSL2

Hi. I would like to experiment with webgpu on wsl, but when I tried running my code with deno, I couldn't request adapter.

console.log(await navigator.gpu.requestAdapter()) // returns null on WSL2

console.log(await navigator.gpu.requestAdapter()) // returns null on WSL2

I tried running nvidia-smi to make sure that I can access my gpu
