How can I change and marker/pin icon on custom map using XamarinFormsMaps?

Question

I need to customized my pins/markers, I already added all the renderers and classes need it but I still don't know how to change the marker and place an image.

I followed the steps from Microsoft https://learn.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/custom-renderer/map-pin#consuming-the-custom-map

My question is in the map implementation

CustomPin pin = new CustomPin
        {
            Type = PinType.Place,
            Label = "Test pin",
            Position = new Position(37.79752, -122.40183)
        };
        map.CustomPins = new List<CustomPin> { pin };
        map.Pins.Add(pin);

What do I have to add/change to place an image that I already have in the resources as the marker of this pin?

For now it takes only the image named pin.png which I as a pin, but need also sometimes to use a different image

The renderer have this:

protected override MarkerOptions CreateMarker(Pin pin)
        {
            var marker = new MarkerOptions();
            marker.SetPosition(new LatLng(pin.Position.Latitude, pin.Position.Longitude));
            marker.SetTitle(pin.Label);
            marker.SetSnippet(pin.Address);
            marker.SetIcon(BitmapDescriptorFactory.FromResource(Resource.Drawable.pin));
            return marker;
        }

Selects directly Resource.Drawable.pin and maybe it's possible to call this and change it, but I don't know how to use it.

I know this is an old question but I will reply for purposes of futures queries that will coming until here. You can add your image at Assets folder and change:

BitmapDescriptorFactory.FromResource(Resource.Drawable.pin) by BitmapDescriptorFactory.FromAsset("pin.png")
