Export model with new features

[EvilEl]

Description

I added a new group to the scene, but when exporting this group is not, can you tell me how to fix it?

 const material = new MeshBasicMaterial({ color: 0x00ff00 });
 const geometry = new BoxBufferGeometry(1, -1000, 1);
 const сub = new Mesh(geometry, material);
 const correlatedSceneGraph = Object.getOwnPropertySymbols(model)[7];
 const group = new Group();
 group.add(cubeA);
 correlatedSceneGraph.add(group)
