Hi, I don't know whether here is the right place for this post. Currently, I am developing my custom addon for combat assisting in Eden's promise. For my use case, I need some APIs like RenderManager:DrawConeFilled(x, y, z, heading, radius, angle, color) to draw the omen of invisible spells. However, I can't find any related documents at this point. Could you please help me and give some examples? I think this has been already supported since we can render navigation meshes.
