How to "Arc Teleportion" with HoloToolKit

Can you tell me how to implement arc teleportion?

I'm developing WindowsMR app in Unity 2017.3.

I'm building a WindowsMR application.
I'm struggling with player teleportion issue.

I want to implement "Arc Teleportion".
(like in a Cliff House, WindowsMR tutorial.)

Holotool Kit has a teleportion demo.
But It can only move lower than the player height.

I would like to teleport to the rooftop of the building like in the cliff house as turning down the joy stick.

I found the similar issue in this forum.
But It didn't work for me.
