'editor' is not defined, and unable to access editor methods in react hooks

[linonetwo]

the-graph/examples/demo-full.js

Lines 62 to 64 in 6f6823f

	function fitGraphInView() {
	editor.triggerFit();
	}

This is undefined.

And how to access those exitor.xxx methods?

const appContainerReference = useRef<HTMLDivElement>(null);

<TheGraph.App
ref={appContainerReference}
/>

This only get null and said

React.createFactory() is deprecated and will be removed in a future major release. Consider using JSX or use React.createElement() directly instead.
Warning: Function components cannot be given refs. Attempts to access this ref will fail. Did you mean to use React.forwardRef()?
Warning: componentWillReceiveProps has been renamed, and is not recommended for use. See https://reactjs.org/link/unsafe-component-lifecycles for details.
