Check if a polygon Graphic contains another Graphic

Question

I have a region item consisting of 4 corners and a polygon constructed by those corners. I want to alert the user when another moving Graphic (simple one with a marker) enters into that polygon. How can I understand that my region contains a specific Graphic?

GeometryEngine::contains(const Esri::ArcGISRuntime::Geometry &geometry1, const Esri::ArcGISRuntime::Geometry &geometry2)  seems to be the solution.
