How to use the react-union.PrescanContext.Provider function in react-union

const render = async (reactElement, routes, applicationContext) => {
		const scanResult = scan(original_$);
		const { widgetConfigs } = route(routes, scanResult);
		const context = { head, body, ...httpContext, ...applicationContext };

		// NOTE: https://github.com/faceyspacey/react-universal-component#static-hoisting
		// Without calling this function, `getInitialProps` statics will not be defined.
		hoistComponentStatics(widgetConfigs);

		initialProps = await resolveInitialProps(context, widgetConfigs);

		const wrappedElement = React.createElement(
			PrescanContext.Provider,
			{ value: { initialProps, widgetConfigs } },
			reactElement
		);

		// NOTE: https://github.com/faceyspacey/react-universal-component/issues/74
		// We are doing this to make sure that the next `flushChunkNames()` call will only contain
		// the universal components from `renderToString`, not from other asynchronous requests.
		flushChunkNames();
		const reactHTML = ReactDOMServer.renderToString(wrappedElement);
		chunkNames = flushChunkNames();

		const react_$ = cheerio.load(reactHTML);

		// NOTE: Here we are populating the original HTML with the widget content.
		react_$('[data-union-portal]').each((_, widget) => {
			const $widget = react_$(widget);

return { widgetConfigs: [], chunkNames: [], initialProps: {} };
		}

		const { widgetConfigs } = route(routes, scanResult);

		// NOTE: https://github.com/faceyspacey/react-universal-component#static-hoisting
		// Without calling this function, `getInitialProps` statics will not be defined.
		hoistComponentStatics(widgetConfigs);

		const initialProps = await resolveInitialProps(
			{ ...context, ...applicationContext },
			widgetConfigs
		);

		const wrappedElement = React.createElement(
			PrescanContext.Provider,
			{ value: { initialProps, widgetConfigs } },
			reactElement
		);

		// NOTE: https://github.com/faceyspacey/react-universal-component/issues/74
		// We are doing this to make sure that the next `flushChunkNames()` call will only contain

		flushChunkNames();
		const reactHTML = ReactDOMServer.renderToString(wrappedElement);
		const chunkNames = flushChunkNames();

		const react_$ = cheerio.load(reactHTML);

		react_$('[data-union-portal]').each((_, widget) => {
			const $widget = react_$(widget);
			const id = $widget.data('union-portal');
