How to use the @projectstorm/react-diagrams.PortModelAlignment.BOTTOM function in @projectstorm/react-diagrams

//3-C) link the 2 nodes together
	var link1 = port1.link(node2.getPort(PortModelAlignment.LEFT));
	var link2 = port3.link(node2.getPort(PortModelAlignment.RIGHT));

	var node4 = new DefaultNodeModel('Node 4', 'rgb(0,192,255)');
	var port4 = node4.addOutPort('Out');
	node4.setPosition(200, 10);

	var link3 = port4.link(node2.getPort(PortModelAlignment.TOP));

	var node5 = new DefaultNodeModel('Node 5', 'mediumpurple');
	var port5 = node5.addInPort('In');
	node5.setPosition(400, 300);

	var link4 = port5.link(node2.getPort(PortModelAlignment.BOTTOM));

	//4) add the models to the root graph
	model.addAll(node1, node2, node3, link1, link2, node4, link3, link4, node5);

	//5) load model into engine
	engine.setModel(model);

	//6) render the diagram!
	return (
		
			
		
	);
