How to implement click and keyboard events in the "Sanderling.Sample.Read" project

In the “ToScriptExtension” file, all functions require “IHostToScript”

for example “MouseClick”

	static public MotionResult MouseClick(
		this IHostToScript host,
		IUIElement destination,
		MouseButtonIdEnum mouseButton) =>
		host?.MotionExecute(destination.MouseClick(mouseButton));

can anybody write me the code to get “IHostToScript”
