I'm trying to add indoor routing to our HERE map. I'm trying to use the example from the sample site to start with. However I don't know the longitude and latitude of the rooms in our building, or the levelId. Is it possible to get this data from api?

below is the code I'm using:

function addRouteToMap(map) {
  let venuesRoute = venuesService;
  venuesRoute.calculateRoute({
    origin: { coordinates: [47.450022, 8.563396]},
    destination: { coordinates: [47.451259,8.560136], venueId: 24860, levelId: 9049 },
    transportMode: 'pedestrian',
    avoid: { features: 'elevator' }
  }).then((result) => {
    // Get objects for the calculated route
    const route = new H.venues.Route(result.routes[0]);

    const indoorObjects = route.getIndoorObjects();
    // Link route map objects with the Indoor Map levels for automatic visibility updates:
    for (let venueId in indoorObjects) {
      for (let levelIndex in indoorObjects[venueId]) {
        const venue = venuesProvider.getVenue(venueId);
        const objectGroup = indoorObjects[venueId][levelIndex];
        map.addObject(objectGroup);
        venue.setMapObjects(objectGroup.getObjects(), levelIndex);
      }
    }
    // Get H.map.Group that contains map objects representing outdoor segments:
    const outdoorObjects = route.getOutdoorObjects();
    map.addObject(outdoorObjects);
  });
}
