Hi I would like to save my Mesh e.g. I have created sphere

 const geometryData = selectedShape.geometry.toJSON();
 const materialData = selectedShape.material.toJSON();
   const meshData = {
        position: selectedShape.position,
        rotation: selectedShape.rotation,
        scale: selectedShape.scale
    };
 const mesh =  JSON.stringify({
      geometry: geometryData,
      material: materialData,
      mesh: meshData
  });
  localStorage.setItem('myobj',mesh);

and to restore I am trying

const mydata =   localStorage.getItem('myobj');
const jsonMydata = JSON.parse(mydata);
const gg = jsonMydata.geometry;
const mm = jsonMydata.material;

let restoredMesh = Mesh(gg,mm);
scene.add(restoredMesh);

But I am not able to retore with this. Could someone suggest how to save Mesh with geometry and material and restore it? Thank you!
