How do I get a Terrain Map in UI Controls HERE Maps v3.1

Question

After upgrading to the v3.1 Javascript SDK with vector/WebGL rendering, there is now no terrain layer in the default UI Controls.

I have looked into the API documentation but there is no clear example that I could find that shows how to specify what shows up in the UI Controls.

    var platform = new H.service.Platform({
            apikey: 'key'
    });

    var layers = platform.createDefaultLayers();

    var hereMap = new H.Map(
        document.getElementById(mapCanvasDiv),
        defaultLayers.vector.normal.map,
        {
            zoom: mapOptions.zoom,
            center: mapOptions.center
    });

    var ui = H.ui.UI.createDefault(hereMap, defaultLayers);

    // Guessing I can change "ui" in some way to include the terrain layer which is a raster layer.

    hereMap.UIControls = ui;

I'd like to have Normal, Terrain and Satellite layers in the UI Controls like when we were on v3.0 as some of our customers use this layer.

Please see below two links about

"Setting the base map type". https://developer.here.com/documentation/maps/topics/map-types.html

"Raster" https://developer.here.com/documentation/maps/topics/raster.html

"H.ui.MapSettingsControl.Options" https://developer.here.com/documentation/maps/topics_api/h-ui-mapsettingscontrol-options.html#h-ui-mapsettingscontrol-options

In order to use satellite and terrain please use raster map type.

defaultLayers.raster.terrain.map
defaultLayers.raster.satellite.map

For example to customize Map Setting Control

var defaultLayers = platform.createDefaultLayers();
var map = new H.Map(document.getElementById('map'),
    defaultLayers.raster.terrain.map, {
    center: {lat: 52.51477270923461, lng: 13.39846691425174},
    zoom: 13,
    pixelRatio: window.devicePixelRatio || 1
});
var ui = H.ui.UI.createDefault(map, defaultLayers);
//remove default mapsettings control
ui.removeControl("mapsettings");
// create custom one
var ms = new H.ui.MapSettingsControl( {
    baseLayers : [ { 
      label:"normal",layer:defaultLayers.raster.normal.map
    },{
      label:"satellite",layer:defaultLayers.raster.satellite.map
    }, {
      label:"terrain",layer:defaultLayers.raster.terrain.map
    }
    ],
  layers : [{
        label: "layer.traffic", layer: defaultLayers.vector.normal.traffic
    },
    {
        label: "layer.incidents", layer: defaultLayers.vector.normal.trafficincidents
    }
]
  });
ui.addControl("customized",ms);

Happy coding!
