RayInteractor -> Data (Optional field)

Hello,
I'm working on pointer events and the RayInteractor -> Data field seems to be exactly what I need.
Reading the helper text gives me the impression that I can assign the current eventData to the RayInteractor to identify and match an event with the RayInteractor. Which is what I want.
But i'm not understanding how to utilize this Data field.
It only takes an Object, meaning it can be pretty much anything from a sprite to a gameobject and I don't see how that works.
The documentation doesn't tell me much, perhaps someone understands it better than me.

Does anyone have an idea?
