Unity 2017 and HTC Vive

Question

According to the documentation of Unity, I should use Axis1D.SecondaryIndexTrigger to be able to detect if the user pushes the joystick's trigger identified by the number 7 (on the image of the HTC Vive and in the table describing the inputs, both are displayed in the above link).

However, when I type if(Input.GetAxis(Axis1D.SecondaryIndexTrigger)), the compiler says :

error CS0103: The name `Axis1D' does not exist in the current context

Axis1D seems to be necessarily imported or somewhat to be usable. How could I do this ?
