Help with mesh discombobulator

Can someone explain how to use mesh discombobulator in Blender?
I’ve made a cube but the plugin does nothing to it. What are the conditions to work?

it works on selected faces (select faces you wish to discombobulate in edit mode, then from object mode press discombobulate

Thanks. And you can’t use it on non-quad faces. Is it possible to update the plugin for non-quad faces?
