InstancedBufferGeometry & glsl -> uv texture question

Hello hi,
I’d like to ask you a question about threejs Instant Buffer Geometry & glsl.

The screenshot above is what the Blender editor window.
As you can see, the instanced particles have a color value according to the texture coordinates uv of a mesh.
only need to check the “From Instancer” function in the Texture coordinate that is the material node of the blender.
(super simple)

I want to make the same result as Blender with glsl shader in threejs.
I’ve seen and tested quite a few examples for this, but I haven’t realized it yet.
If there is an example or code or hints like this, I would like to know.
