How to use the @projectstorm/react-diagrams-core.DefaultDiagramState function in @projectstorm/react-diagrams-core

export default (options: CanvasEngineOptions = {}): DiagramEngine => {
	const engine = new DiagramEngine(options);

	// register model factories
	engine.getLayerFactories().registerFactory(new NodeLayerFactory());
	engine.getLayerFactories().registerFactory(new LinkLayerFactory());
	engine.getLayerFactories().registerFactory(new SelectionBoxLayerFactory());

	engine.getLabelFactories().registerFactory(new DefaultLabelFactory());
	engine.getNodeFactories().registerFactory(new DefaultNodeFactory()); // i cant figure out why
	engine.getLinkFactories().registerFactory(new DefaultLinkFactory());
	engine.getLinkFactories().registerFactory(new PathFindingLinkFactory());
	engine.getPortFactories().registerFactory(new DefaultPortFactory());

	// register the default interaction behaviours
	engine.getStateMachine().pushState(new DefaultDiagramState());
	return engine;
};
