I have a database with the latitude and longitude of an adress. 

 When I click on the marker a kind of "native" window of Apple Maps opens showing the location. That's fine for me, but then you have to click on the field and again on the marker. So I made a formula field and a button, clicking on this button opens Apple Maps and shows a marker on the location. But is it possible to open the "native" map from Ninox instead? How do I do this?
