Volume Contour with Image Cropping Widget simultaneously (vtk.js)

Hello i’m new to vtk and i working in a project that we need to load a model from dicom files and be able to do some basic features, some of kitware github examples are exactly what we need. Image Cropping and Volume Contour.

Image Cropping Widget: https://kitware.github.io/vtk-js/examples/ImageCroppingWidget.html
Volume Contour: https://kitware.github.io/vtk-js/examples/VolumeContour.html

The issue i facing each one of them uses a different actor and mapper, vtkVolume and vtkVolumeMapper on Image Cropping, and for Volume Contour are vtkActor and vtkMapper.

I know you guys probably gonna suggest using multiple viewports and renderers and i’m fine with it, but if so how i could be able to send a pipeline output to another one. For example, on Volume Contour viewport when iso value has changed how i update the Image Cropping viewport to load current model that is now in Volume Contour viewport?

I have no clues on how to do that, i would be much appreciate if someone helps me figure out.
