Colorbar / colormap for scalar in dash vtk view

Is it possible to show a colorbar in dash vtk viewer?
I want a colorbar like this with 3D mesh view in dash vtk viewer.

Did you or someone else find a solution to this?

I could not find anything anything about this, except this workaround where a colorbar is added using an empty plotly go.Figure()

The feature is already available in the current version of the underlying JS framework. There is a PR on the way to update dash-vtk.


is this showScalarBar options that is already available on the master release of dash-vtk?
