Navigate to new URL from within MemoryRouter structure - reactjs

Question

When a user completes a booking process and navigate to the confirmed details view. I need the URL to change. This is proving to be difficult to work around as the routing in done through MemoryRouter which can neither read, nor write to the URL. I need to break one of the views out and have the browser navigate to this new view.
I have tried breaking out from one router and creating a second that would return based on the original URL, then tried the very hacky window.location and direct the url to the new router.
import React from 'react';
import { MemoryRouter, Route, Switch } from 'react-router-dom';
import {
Page,
StartScreen,
StoreSearch,
ServiceSelector,
StoreSelector,
OptionSelector,
AppointmentForm,
AppointmentDetails,
ConfirmationScreen,
ErrorScreen,
} from 'components';
import { WithPageTitle, ScrollToTop } from 'containers';
import { services } from 'utilities';
const NewAppRouter = () => {
return (
<MemoryRouter>
<ScrollToTop>
<Switch>
<Route exact path="/" component={StartScreen} />
<WithPageTitle>
{pageTitle => (
<Page pageTitle={pageTitle}>
<Route path="/zip" component={StoreSearch} />
<Route path="/services" component={() => ServiceSelector({
services: services.services,
withBackButton: true,
backTo: "/zip"
})} />
<Route path="/stores" component={StoreSelector} />
<Route path="/options" component={OptionSelector} />
<Route path="/form" component={AppointmentForm} />
<Route path="/details" component={AppointmentDetails} />
{/* <Route path="/confirmation" component={ConfirmationScreen} /> */}
<Route path="/error" component={ErrorScreen} />
</Page>
)}
</WithPageTitle>
</Switch>
</ScrollToTop>
</MemoryRouter>
)
}
const AppRouter = () => {
if(window.location.href="http://localhost:9998"){
return (
<NewAppRouter />
)
} else if (window.location.href="http://localhost:9998/confirmation") {
return (
<ConfirmRouter />
)
} else {
return console.error('Route Not Found')
}
}
export default AppRouter;
