Access property of viewer object

[nizartaha]

How do i access a property of a viewer object to update it?
for example, i could update pt cloud points with pointcloudobj._data = pt_cloud.points . how do i access the colors (or pointsize) and update them?

  pt_cloud, colors = load_point_cloud()
  pointcloudobj._data = pt_cloud.points
  # pointcloudobj._data['color'] = colors  # does not work
  pointcloudobj.update()
  viewer.view.update()

i have compas_view2 0.5.0
Thanks

I could find the solution in bufferobject init definition here: src/compas_view2/objects/bufferobject.py . its pointcloudobj.pointcolors = colors
i will close the issue , but compas_view2 would need eventually better Documentation
