Vive pro2 hand tracking

[Naira06]

I'm using VIVE pro2 in unity project, my project goal to use hand tracking in interaction.
my project succseulfy track hands now the problem  i want a ray from the hands to choose and interact with objects in unity which doesn't work , i only get the ray but it doesn't interact.
i tried to use vive input utility packege samples I only get vive trackes with ray and I can't interact with any object  or even to select.
If anyone knows how to solve this or its regarding coding?
