In the security solution, we are having different routes like

• app/security/overview
• app/security/alerts
• app/security/hosts
• etc...

we would like to redirect the route app/security to app/security/overview by doing that

  core.application.register({
      id: 'security',
      title: 'Security',
      appRoute: 'app/security',
      navLinkStatus: AppNavLinkStatus.hidden,
      mount: async (params: AppMountParameters) => {
        const [{ application }] = await core.getStartServices();
        application.navigateToApp(`${APP_ID}:${SecurityPageName.overview}`, { replace: true });
        return () => true;
      },
    });

However, when we are doing that, we are breaking all the different routes in our app. Since everything is going to the mount of the route app/security. That's why we think to add an exact property will resolve our problem.
