How to download Landsat8 data from Google Earth Engine

Question

Below is my code and it runs perfectly but when I run the unsubmitted task in gee,it gives this error:

Error: Image.setDefaultProjection, argument 'image': Invalid type. Expected type: Image. Actual type: ImageCollection. (Error code: 3)

var dataset = ee.ImageCollection('LANDSAT/LC08/C02/T1_L2')
      .filterBounds(geometry)
      .filterDate('2019-11-17', '2020-03-31')


// Applies scaling factors.
function applyScaleFactors(image) {
  var qaMask = image.select('QA_PIXEL').bitwiseAnd(parseInt('11111', 2)).eq(0);
  var saturationMask = image.select('QA_RADSAT').eq(0);
  
  var opticalBands = image.select('SR_B.').multiply(0.0000275).add(-0.2);
  var thermalBands = image.select('ST_B.*').multiply(0.00341802).add(149.0);
  return image.addBands(opticalBands, null, true)
              .addBands(thermalBands, null, true)
              .updateMask(qaMask)
              .updateMask(saturationMask);
}

dataset = dataset.map(applyScaleFactors);

var visualization = {
  bands: ['SR_B4', 'SR_B3', 'SR_B2'],
  min: 0.0,
  max: 0.3,
};


Map.addLayer(dataset, visualization, 'True Color (432)');

Export.image.toDrive({ 
  image: dataset,
  description: 'Landsat8_for_NDBI',
  scale: 10, 
  maxPixels: 1e13, 
  region: geometry 
});

Can you help me to bypass this?

Use the awesome geetools from Rodrigo E. Principe for exporting an ImageCollection to Drive:

var batch = require('users/fitoprincipe/geetools:batch');

batch.Download.ImageCollection.toDrive(dataset,'Some_folder',{
  scale: 10, 
  maxPixels: 1e13, 
  region: geometry 
});
