/**
* Interaction Prompt Plugin
*
* A plugin that adds a hand pointer icon over the canvas that moves to prompt the user to interact with the 3d scene.
* Pointer icon from [google/model-viewer](https://github.com/google/model-viewer)
*
* The pointer is automatically shown when some object is in the scene and the camera is not moving.
* The animation starts after a delay and stops on user interaction. It then restarts after a delay after the user stops interacting
*
* The plugin provides several options and functions to configure the automatic behaviour or trigger the animation manually.
* TODO - create example
* @category Plugins
