Does Transform Editor work with entities?

I have successfully used Transformation Editor with primitive (tileset), but it’s not clear if it can be used to change position of entity…

var object = new Cesium.Entity({
    name: 'test.glb',
    position: initialPosition,
    orientation: orientation,
    model: {
      uri: 'test.glb',
      maximumScale: 1,
    },
  });

Transform Editor requires bounding box and transform, is there is any way this could be retrieved from the Cesium Entity?

Are there any more direct support channels? On github it’s recommended to ask for support here, but this forum seems not active at all.
