How can I "SET" an input value in the new input system?

[dmal]

I'm trying to make my own custom mobile onscreen controller. The stick will have very custom functionality which I can make.
The problem is that I want to use Unity's new Input system, but I dont know how to SET an input value.
Example: "Horizontal = .65"
All of my searches have only said how to get input values.

I want to use the input system instead of hardcoding it because I am using ECM2 character controller.

Appreciate any help you can give
