from geetools.utils import initialize_documentation

  '2': 'dark',
  '3': 'shadow',
  '7': 'clouds_low',
  '8': 'clouds_mid',
  '9': 'clouds_high',
  '10': 'cirrus'
}
image = ee.Image("COPERNICUS/S2_SR_HARMONIZED/20230120T142709_20230120T143451_T18GYT")
decoded = image.geetools.classToBands(class_info, "SCL")
