Hi, is possible to extend maps app through app extensions to add some road marks or something like that when user uses navigation? I want to show some checkmarks on apple maps app when user uses apple maps. Or maybe just to notify users when approaching to some section? If anything from this things is possible than which API to use? I have searched and did not find anything useful expect SiriKit but I think with that API its not possible to achieve this. Thanks Regards
