How do I light a sprite in a 3D environment?

Hi, I'm making a 2.5D game, where 2D sprites are in a 3D environment. I'm using URP and I have a problem with lighting the sprites. The sprites are lighting up from behind, and not front. I tried with directional, spot and point lights but the result is the same no matter what official shader I use they only light up when they receive light from behind. Front light has no effect whatsoever on the sprites.

I spent the entire day looking for a solution but to no avail. Only solution I saw someone else mention is making the game object with the "sprite renderer" on, a child of another gameobject and rotate it 180 degrees on Y. But that is not an option for me cause I'm using custom scripts to rotate that game object already.

So can there be a custom shader? Can one be created using shadergraph maybe? I know some others have faced the same problem but did anyone really solve it?

Thanks.
