Set InputSystemUIInputModule at Run Time?

What is the correct way of setting the InputSystemUIInputModule via C#? I've attempted the following without success...

Code (CSharp):

1. InputSystemUIInputModule uiModule = GetComponent<InputSystemUIInputModule>();
2.  
3. var actions = new MyGeneratedInputSystemClass();
4.  
5. uiModule.point.Set(actions.UI.Point);

As well as...

Code (CSharp):

1. ((InputSystemUIInputModule)EventSystem.current.currentInputModule).point = InputActionReference.Create(actions.UI.Point);

The second gives me an object reference not set error at run time however the IDE shows no issue. I'm unsure which reference is missing?

My Input Action Map is called "UI" and per this example it includes a "Point" action.

 

Second method should work fine at least as of 1.3.

 

I need to do the same but changing it in runtime also changes it it editor mode - this is bananas. Does anyone has any ideas as to change this reliably either in runtime or in editor mode?
