what is the new way to add fog in unlit in urp12?

I used this in urp8.3


but it’s blown out

so i thought it was reversed and removed onminus but now i get other artifacts so I’m wondering what’s the right way to add fog these days, in urp 12

should look like this

looks like that instead when i remove the oneminus
does u2021 break uv2?
