// Create graphic

var graphic = new Graphic({
  geometry: view.center,
  popupTemplate: {
    content: [{
      // add popupTemplate content
    }]
  }
});

var feature = new Feature({

  container: document.createElement("div")
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});
// Specify an already-defined HTML div element in the widget's container

const basemapGallery = new BasemapGallery({
  view: view,
  container: basemapGalleryDiv
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
