Question How do I assign an InputActionReference in code?

I currently have an InputActionReference defined in my class.

Code (CSharp):

1.     private InputActionReference _uiToggle;
2.  

This can be set in the Inspector by dragging an XRI Default Input Actions "XRI LeftHand Interaction/Switch UI" from the Starter Assets folder. I would like to assign this value in code if possible. How do I obtain a reference?

 

With help from this video:

I was able to build the class and use it. Hooray.
