How to add outline for a GeometryInstance or PolygonGeometry in Cesiumjs

I need to draw outline to the polygon primitive drawn with following code :

         scene.primitives.add( new Cesium.ClassificationPrimitive({

            geometryInstances : new Cesium.GeometryInstance({

                geometry : new Cesium.PolygonGeometry({

                    polygonHierarchy : new Cesium.PolygonHierarchy(

                        Cesium.Cartesian3.fromDegreesArray(coords)

                    ),

                    height : height

                }),

                attributes : {

                    color: color,

                },

                id : id,

                description : "Highlight Object",

            })

        }));

Is there any way to draw outline to a polygon primitive? I am aware that it can be added with Entities but the requirement is to use primitives.
Any help is much appreciated.

You can use PolylineCollection as a separate primitive for outline.

I created a demo in Sandcastle showing this use case:

var viewer = new Cesium.Viewer('cesiumContainer');



var coords = [

    -72.0, 40.0,

    -70.0, 35.0,

    -75.0, 30.0,

    -70.0, 30.0,

    -68.0, 40.0

];



var cartesian = Cesium.Cartesian3.fromDegreesArray(coords);



var color = Cesium.Color.DARKRED;

var outlineColor = Cesium.Color.GOLD;



var polygonPrimitive = new Cesium.Primitive({

    geometryInstances: new Cesium.GeometryInstance({

        id: 'polygon',

        geometry: Cesium.PolygonGeometry.createGeometry(

            new Cesium.PolygonGeometry({

                polygonHierarchy: new Cesium.PolygonHierarchy(cartesian)

            })

        )

    }),

    appearance: new Cesium.MaterialAppearance({

        material: new Cesium.Material.fromType('Color', {

            color: color

        })

    }),

    asynchronous: false

});



var polylinePrimitive = new Cesium.PolylineCollection();

polylinePrimitive.add({

    positions: cartesian,

    width: 3.0,

    loop: true,

    material: new Cesium.Material.fromType('Color', {

        color: outlineColor

    })

});



var primitives = viewer.scene.primitives;

primitives.add(polygonPrimitive);

primitives.add(polylinePrimitive);
