Custom Lo-Code for Node

Everything I am reading indicates that you can modify the Node Logic directly. I have started with a base API Call node and then attempting to add additional Inputs. They show up in the node box but I am not able to use them in the code itself. Whenever I modify the code and hit "Save" the changes are lost.

What am I missing?
