Construction of luminous expression methods

Hi,

I am investigating how to emit the following in my visionOS app.

Right now, I'm trying various things with Shader Graph in Reality Composer Pro, but I can't tell from the official documentation and WWDC session videos what the individual functions and combined effects of Reality Composer Pro's Shader Graph nodes are, I am having a hard time understanding the effects of the individual functions and combinations of them. I have a feeling that such luminous materials and expressions are not possible in visionOS to begin with. If there is a way to achieve this, please let me know.

Thanks.
