How to use the ember-inspector/utils/is-route-substate function in ember-inspector

return this.model.filter(routeItem => {
      let currentRoute = this.currentRoute;
      let hideRoutes = this.get('options.hideRoutes');
      let hideSubstates = this.get('options.hideSubstates');

      if (hideRoutes && currentRoute) {
        return checkCurrentRoute(currentRoute, routeItem.value);
      }

      if (hideSubstates && isRouteSubstate(routeItem.value.name)) {
        return false;
      }

      if (!searchMatch(routeItem.value.name, this.searchValue)) {
        return false;
      }

      return true;
    });
  }),
