How can I record eye tracking data with the HTC VIVE SRanipal SDK?

Hello,

I am planning this simulation where I need to collect eye-tracking data, specifically where the user's attention focuses in the environment (what objects they look at and for how long). Is there an easy way to do this and can the screen be recorded as well to see where the user is looking at a given point in time? Or is there any other way that this data can be visualised?

I have available an HTC Vive Pro eye headset, and I have been told to use the HTC VIVE SRanipal SDK, but I have no clue where to start. There are some documents available but being quite new to Unity (and coding in general) I do not understand many of the things listed there.

Thanks!
