How export all bands' pixel value in Google Earth Engine

Question

i want to obtain the pixel values of an image for all bands in Google Earth Engine. My code is wrong(Error: Invalid argument: 'collection' must be a FeatureCollection. (Error code: 3)). I can see data with print. But couldn't export to CSV.

`

var geometry = 
    /* color: #d63000 */
    /* displayProperties: [
      {
        "type": "rectangle"
      }
    ] */
    ee.Geometry.Polygon(
        [[[26.9559366037084, 39.42848463948233],
          [26.9559366037084, 39.41562180312237],
          [26.971214466257226, 39.41562180312237],
          [26.971214466257226, 39.42848463948233]]], null, false);
var kor = ee.Image(ee.ImageCollection('LANDSAT/LC08/C01/T1_TOA')
    .filterBounds(geometry)
    .filterDate('2020-06-01', '2020-8-31')
    .filterMetadata('CLOUD_COVER','less_than',5)
    .sort('CLOUD_COVER')
    
    .first());

var data = ee.FeatureCollection(

  kor.reduceRegion({
  reducer: ee.Reducer.toList(),
  geometry: geometry,
  scale: 30,
  maxPixels: 1e9
}));

print(data);

Map.centerObject(kor)
Map.addLayer(kor,{bands:["B4","B3","B2"],min:0,max:5000})

Export.table.toDrive({
  collection: data,
  description: 'rgbb',

})

I expecting export all bands' pixel values to CSV file
