There are some errors in the document

As shown in the figure

https://sprotty.org/docs/concepts/extension-points/#creating-custom-model-elements

I think the correct code is

import { SEdgeImpl, SNodeImpl } from "sprotty";

export class CustomNode extends SNodeImpl {
}

export class CustomEdge extends SEdgeImpl {
}

Sprotty version is 1.0.0 automatically generated by Yeoman and the Sprotty generator

https://sprotty.org/docs/concepts/extension-points/#creating-custom-views

I think the correct code is

import { ShapeView } from "sprotty";

export class CustomNodeView extends ShapeView
