Error - vectorTileDataset.setStyleSet(styles); not a function - Following Harp.GL tutorial on HERE Dev Portal

[cpandit201]

I am following tutorial posted on HERE Developer portal
https://developer.here.com/tutorials/harpgl/#introduction

Currently was on step to add remote data on map to style
https://developer.here.com/tutorials/harpgl/#add-data-to-the-map

// At the bottom of index.ts
async function addRailRoads() {
    const globalRailroads = new VectorTileDataSource({
        baseUrl: "https://xyz.api.here.com/hub/spaces/hUJ4ZHJR/tile/web",
        apiFormat: APIFormat.XYZSpace,
        authenticationCode: 'ACbs-cqcFI4FlPRLK_VF1co', //Use this token!
    });

    await mapView.addDataSource(globalRailroads);
    const styles = [
        {
            when: ["==", ["geometry-type"], "LineString"],
            renderOrder: 1000,
            technique: "solid-line",
            color: "#D73060",
            opacity: 1,
            metricUnit: "Pixel",
            lineWidth: 1,
        }
    ];
    globalRailroads.setStyleSet(styles);
    mapView.update();
}
addRailRoads();

However I am getting the error on last third line

    globalRailroads.setStyleSet(styles);
index.js:106 Uncaught (in promise) TypeError: globalRailroads.setStyleSet is not a function
    at addRailRoads (index.js:106)
