How can I draw the gradient Polyline with points in Here Map Angular Project?

Question

I am building a website using Angular with Here Map. I am using Here Map Api I tried to draw a gradient line with Polyline but it is not working and I can't know how I can do it.

Here is my code.

                        const points = response.points;
                        if (points && points.length > 0) {
                            this.points = [];
                            points.forEach((point: any) => {
                                this.points.push(point.lat, point.lng, 0);
                            });
                            
                            this.lineString = new H.geo.LineString(this.points);
                            // make the route gradient color
                            const temp = new H.map.Polyline(
                                this.lineString,
                                {
                                    style: {
                                        strokeColor: 'rgb(255, 248, 45)',
                                        lineWidth: 10,
                                    },
                                }
                            );
                            console.log("routeLine====", temp)
                            this.map.addObject(temp);
                        }

This shows me yellow line. but I want to draw gradient line (yellow and red color) like google map.

Please help me. Thanks.

At the moment Here Map Api does not support for gradient polylines. It currently supports only solid colors for route and their outlines
