Why my sprite isn't getting shadows (Shadow graph URP)

This is my first time posting so feel free to correct me in any way.

I'm going soon to start a project with people, they asked me to be able to make sprites that receive and cast shadows in a URP 3D world so I started messing around.

This is what I got after watching many tutorials from all over the internet:

What might it be? I turned Cast Shadows and Receive Shadows in both (With debug view). This is my shader graph: [The main texture is a built-in Triangle texture but changing it to Square during gameplay affected nothing]
