How to use the ember-flexberry-designer/objects/uml-primitives/fd-uml-partition.Partition function in ember-flexberry-designer

let objectInState = new ObjectInState({
        position: { x: 600, y: 200 },
        size: { width: 100, height: 50 },
        name: 'name',
        state: 'state'
      });

      let activeState = new ActiveState({
        position: { x: 600, y: 300 },
        size: { width: 100, height: 50 },
        name: 'name',
        state: 'state'
      });

      let partition = new Partition({
        position: { x: 600, y: 350 },
        name: 'partition'
      });
