    import MVT from 'ol/format/MVT.js';
    import VectorTileLayer from 'ol/layer/VectorTile.js';
    import OGCVectorTile from 'ol/source/OGCVectorTile.js';

    const map = new Map({
      target: 'map',
      layers: [
        new VectorTileLayer({
          source: new OGCVectorTile({
            url: 'https://maps.gnosis.earth/ogcapi/collections/NaturalEarth:cultural:ne_10m_admin_0_countries/tiles/WorldCRS84Quad',
            format: new MVT(),
            projection: 'EPSG:4326',
          }),
