Post processing not working on LWRP

Hey I’m using Unity 2019.3 and the post processing effects don’t work when I’m on the LWRP. i don’t know if this is a bug or im missing something?

The URP (same as LWRP) doesn’t work with the Post Processing V2 stack package. You need to use the URP-specific post-processing features.
