Control UI with Vive Touchpad axis [Steam VR plugin & Playmaker]

Hi everyone !

I've looked a lot in the web but I haven't found yet.
I'm looking to control a canvas with 3 buttons by pressing the different axis of the touchpad :

• Touchpad UP : previous button.
• Touchpad DOWN : next button
• Touchpad RIGHT: click (this one is easy)

I've set up the Unity EventManager and the arroys work but I haven't found how to map...
