Quick Question: Are you using any VR spatial & biometrics analytics tools?

Hey everyone I came across Cognitive3D's SDK thanks to a talk from AWE 2023 made by the founder. I'm extremely curious about these new VR analytic tools. I'm pretty sure the are more out there. But has anyone used this one to gain insights on user actions and eye tracking? Is it easy to integrate with Unity or Unreal Engine? Or are there other analytics tool that anyone else recommends?

Love to hear everyone's thoughts. Thanks a bunch!
