Input System: How do you read a single axis value?

I am trying to detect one axis using the Input system using version 1.0.1. I have generated a C# class from the Input Actions. How would I read the value from the axis.

This is the code that I have so far. What would I put as the value type?

controls.Transform.Rotate.performed += ctxt => r = ctxt.ReadValue<>();

Hi,

today I got same problem and I find a solution.

rollInput.ReadValue()

this is how I do it.
