Autodesk Maya plugin. Shade faces in UV Editor with material color

I need a Autodesk Maya plugin that will shade faces in UV Editor with their material color. E.g. there is plane with 4 faces in the scene. Different shaders with different colors are applied to every face, so every face in UV Editor should be shaded with corresponding material color (see attachment [login to view URL], [login to view URL]). Should be able to enable/disable shading with a MEL command. The Plugin must work for Maya 2020. The Plugin must be implemented with Maya NET API. Microsoft Visual Studio project and compiled .[login to view URL] library of a plugin must be submitted as a result. Scene for testing is in attachment.
