Accessing an EditorUtilityWidget in Python

I’m trying to build a UI in Python as it’s easier for me to parse incoming data that way. I’m not very familiar with casting on Blueprint so I’m having this issue. I was using Construct from Class and it was working correctly but Python doesn’t seem to have that method.
The button template (AssetButton) is an Editor Utility Widget that I assume it’s a synonim for WidgetBlueprintGeneratedClass (?).
Would some kind of “new_button = AssetButton()” kind of thing work? How are those imported into the inline Python?

Thanks!
PS: I’m just trying some stuff, eventually I’ll move everything to an external py file.

Here’s the error
