Is there a different way to get the menu in this simple Open3D Python script?

This Python 3.12 and Open3D 0.19.0 script on Ubuntu 24.04:

import open3d as o3d c0 = o3d.geometry.TriangleMesh.create_cylinder(0.5, 5) c0.paint_uniform_color([0.1, 0.9, 0.1]) c0.compute_vertex_normals() c1 = o3d.geometry.TriangleMesh.create_cylinder(0.5, 5) c1.paint_uniform_color([0.9, 0.1, 0.1]) c1.compute_vertex_normals() c1.translate([1, 1, 0]) o3d.visualization.draw(c0+c1, raw_mode=True) # o3d.visualization.draw_geometries([c0, c1])

displays a window with a menu:

but when I use draw_geometries (commented line) instead of draw, there is no menu. Do I have to merge geometries c0 and c1 and use draw to get the menu? I'm looking for a simple way of doing it, without resorting to open3d.visualization.gui.Application.instance.
