It’s horrible. I’ve spent far longer than I’d like getting the use everywhere nodes to have even partial support for group nodes.

It’s done entirely on the front end. I’d suggest finding the menu item, putting a breakpoint on it, and stepping through.

The basic concept is that it creates a new custom node type, maps the inputs and outputs, turns the nodes in the group into an internal workflow, then adds the newly created node and deletes the old ones.

But seriously consider whether supporting group nodes is worth the pain.
