How to use the mwp-store/lib/browser.getInitialState function in mwp-store

export function resolveAppProps(
	routes: Array,
	reducer: Reducer,
	middleware: Array = []
): Promise {
	const basename = window.APP_RUNTIME.appContext.basename || '';
	const findMatches = getFindMatches(routes, basename);
	const createStore = getBrowserCreateStore(findMatches, middleware);
	const store = createStore(reducer, getInitialState(window.APP_RUNTIME));

	// find the matched routes, and then resolve their components - mutate
	// the route object so that the overall `routes` object contains
	// resolved `component` properties for the current location
	const resolveComponents = (): Promise => {
		// get an array of matched routes
		const matchedRoutes = findMatches(window.location);
		// resolve components in parallel (AJAX chunk requests)
		return Promise.all(
			matchedRoutes.map(matchedRoute => {
				if (matchedRoute.route.getComponent) {
					return matchedRoute.route.getComponent();
				}
				return Promise.resolve(matchedRoute.route.component);
			})
		).then(components => {
