For VR Game Devs - Is anyone using software to gain insights in your VR APP?

Hey everyone I came across Cognitive3D thanks to AWE 2023. I’m curious about VR analytic software. I’m pretty sure the are more out there. 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?

Appreciate your opinions and experience with these.
