RFI: UI Particle using Shader graph

[mwieliczuk]

I want to use Screen space overlay render mode on the Canvas.
The UIParticleSystem script works with shaders included in this package and I wanted to know if it could be written in a shader graph. I work on URP.
In Shader Graph I have information about shape and alpha but I don't have color information.
It's always dark blue. Is it possible to create a graph shader that would work with this script?
There is my shader.

A custom function that I used is a simple in-out function where I tried to add pragmas.
Without the custom function shader works in the same way.
