Obtaining coordinates of TUniMapVector

[Askhat]

   This code adds on UniMap a polyline:
   
   with UniMap1.Vectors.Add do
     begin
       AddPoint(lat1, lng1);
       AddPoint(lat2, lng2);
       AddPoint(lat3, lng3);
       VectorType:=mvPolyline;
       with Options do
       begin
         ...
       end;
       AddToMap;
       FitBounds;
   end;
   
   How to retrieve the coordinates of the polyline after editing?
