Resolved Mouse ScrollWheel with 1DAxis

I'm trying to get the scrollwheel to work with 1DAxis. I can get it to work by setting "Which Side Wins" in the editor but can't work out to do it in code.

Spoiler: Add via code

Code (CSharp):

1. action = UnityEngine.InputSystem.InputActionSetupExtensions.AddAction(
2.             actionMap, "ZoomLook", UnityEngine.InputSystem.InputActionType.Value, null, null, null, null, "Axis");
3. if (action != null)
4. {
5.     UnityEngine.InputSystem.InputActionSetupExtensions.AddCompositeBinding(action, "1DAxis")
6.          .With("Positive", "<Keyboard>/rightBracket", "Keyboard&Mouse")
7.          .With("Negative", "<Keyboard>/leftBracket", "Keyboard&Mouse");
8.  
9.     UnityEngine.InputSystem.InputActionSetupExtensions.AddCompositeBinding(action, "1DAxis")
10.         .With("Positive", "<Gamepad>/dpad/up", "Gamepad")
11.         .With("Negative", "<Gamepad>/dpad/down", "Gamepad");
12.  
13.     UnityEngine.InputSystem.InputActionSetupExtensions.AddCompositeBinding(action, "1DAxis")
14.          .With("Positive", "<Mouse>/scroll/y", "Keyboard&Mouse")
15.          .With("Negative", "<Mouse>/scroll/y", "Keyboard&Mouse");
16.  
17. }

I'm using the verified 1.0.0 in U2019.3. For some reason, I'm not sure why, if I leave "Which Side Wins" to neither it does nothing.

So, how can I set "Which Side Wins" in an editor script?

 

Found the answer in the v1.1 preview-2 documentation.

Spoiler: Solution

Code (CSharp):

1. UnityEngine.InputSystem.InputActionSetupExtensions.AddCompositeBinding(action, "1DAxis(whichSideWins=1)")
2.      .With("Positive", "<Mouse>/scroll/y", "Keyboard&Mouse")
3.      .With("Negative", "<Mouse>/scroll/y", "Keyboard&Mouse");
