Draggable Annotations

Hello,
I am trying to make an annotation draggable. I tried setting the isEditable property to true, but nothing happened. I can’t find the right documentation for draggable annotations . My code for creating the Annotation it’s below:

sciChartSurface.annotations.add(new LineAnnotation({
    stroke: "#279B27", strokeThickness: 3,
    xCoordinateMode: ECoordinateMode.DataValue,
    x1: 0,
    x2: 0,
    yCoordinateMode: ECoordinateMode.Relative,
    y1: 0,
    y2: 1,
    isEditable: true,
}));
