How to embed "draw_geometries_with_editing" into "Application.instance"?

Hi All,

I don’t need many functions of “draw” and “O3DVisualizer”, but I need to customize the point cloud selection function according to my needs. So, I need to embed “draw_geometries_with_editing” into “Application.instance” or other methods that can achieve the same effect.

For example, I need the “Selection Sets” function in “Mouse Controls”, and can output the selected point cloud set. In addition, it is also what I need to display different colors according to the point cloud segmentation results.

I really appreciate if anyone can help. Thanks
