Question Vive button layout in XR interaction toolkit

Hi!
A simple question that drives me crazy. I am using the Vive controller and want to do something as simple as teleport, which works and is by default bound to the vive grip button. Now I want to do switch this to the trigger button, but I can not figure out how to do this as I do not know which Vive Buttons correspond to which XR interaction toolkit input action.

Any help is greatly appreciated.
Thanks!
