How to zoom in on a cluster in Yandex Maps?

Question

Yandex maps

Hello!
Please tell me how, with clusterDisableClickZoom=true, to programmatically zoom in on a cluster on Yandex maps in the same way as it is done by clicking on it?
I try like this:

objectManager.clusters.events.add('click', function onObjectEvent (e) {
               var objectId = e.get('objectId');

               var obj = ObjectManager.clusters.getById(objectId);
     
                if (myMap.getZoom()<16)
                {
                    //приближаем кластер
                    map.setBounds( obj.getBounds() );
                }else{
                    //Показываем балун
                }

}

doesn't want to... obj.getBounds() - gives error
