How to show MapPin label in Xamarin.Forms.Maps?

I have added a Label in MapPin of Xamarin.Forms.Maps but it is not displaying on UI.

Code:
Pin MapPin = new Pin();
MapPin.Type = PinType.Generic;
MapPin.Position = new Position(SelectedBenefit.latitude,
SelectedBenefit.longitude);
MapPin.Address = SelectedBenefit.street_address;
MapPin.Label = "Benefit Location"; // This text is not appearing on UI
BenefitMap.Pins.Add(MapPin);

Is there any workaround for this?
