// A Sentinel-2 surface reflectance image.
var img = ee.Image('COPERNICUS/S2_SR/20210109T185751_20210109T185931_T10SEG');

// A small region within the image.
var region = ee.Geometry.BBox(-122.0859, 37.0436, -122.0626, 37.0586);

var downloadId = ee.data.getDownloadId({
    image: img,
    name: 'single_band',
    bands: ['B3', 'B8', 'B11'],
    region: region
});
print('Single-band GeoTIFF files wrapped in a zip file',
