Question Custom Lighting with unlit shader graph doesn't receive shadows

I'm trying to make my own toon shader with unlit shader graph and custom lighting, but apparently, it doesn't receive any shadow from other shadow casters. I made custom lighting by following this tutorial => https://blog.unity.com/engine-platform/custom-lighting-in-shader-graph-expanding-your-graphs-in-2019
How can I make this receive shadows?

 

This package has all the custom nodes you need for lights and such:
https://github.com/Cyanilux/URP_ShaderGraphCustomLighting

It currently works for me on 2022.2.
Some nodes might be deprecated but Main Light and Main Light Shadows works at least.

 

I am getting this issue with custom light. Do you know why its happening?
