How do I create gradient turbulence orb like this?

Hi all,

I am looking to create visual effect like the image below, and wondering what the best practice might be?
I am thinking there might be two ways, one is to use vfx graph (I am new to vfx and not sure if I can achieve effect like this), or create a video in after effects and use the video as texture applied to a sphere in unity. I am wondering if anyone has experience creating something like this? Any suggestions or tutorial resources will be appreciated!!! Thanks in advance.

Is it just a fancy looking orb you're trying to make, or does the 3d mesh surface of the orb, animate too?
