How to create a light burst / shiny sheen effect on TextMesh Pro?

Hi everyone!

I’m trying to create a “light burst” effect or a subtle shine on a TextMesh Pro text component (like a flash of light moving across the text). I believe it’s the effect shown in the image (I want to recreate that exact look).

I’m looking for something similar to the references below:

What is the best way to do this nowadays? Should I create a custom Shader Graph (URP), or is it better to use standard UI Masking and an animation?

If anyone could provide a step-by-step guide or share a simple Shader Graph setup for this, I’d really appreciate it!

Thanks in advance!
