Why not working light in Unity 2021.2.7f1 in 2D project?

Hy guys,

I have a 2D project and I would like to have lighting for my project, but it does't work.
I have Unity 2021.2.7f1.
I made this steps:

1) Window-> Package manager -> Install Universal RP 12.1.2
2) Create -> Rendering -> URP Asset (with Universal Renderer) (I tried with URP Asset with 2D Renderer but it didn't work with that either) 3) Edit -> Project settings -> Graphics and I add called Universal

4) Window -> Rendering -> Render pipeline converter -> Material and Material reference Upradge -> Initialize Converters -> Convert Assets
And I see that every sprites in the scene material became "Sprite-Lit-Default".
I make these settings but nothing happens.
What's the problem? I forgot some steps?
