[How to render skeleton with 2d mode]

First, I'm not very good at English so bare with me.

I'm currently working on the Sample scene in the Hand tracking sdk in Unity. 

I'm using XR settings of Google Cardboard which doesn't support Skeleton mode.(I suppose I'm on the 2d point mode)

But can I render the skeleton model with the 21 points returned by the GestureInterface.cs(with the fake z coordinate)?

I know it will seem weird but I would really want those skeleton to show

Is there a way to render the hand skeleton with the 2d mode points returned (with a fake z factor) from Gesture Interface script?
