Google Earth Engine - How to make the sentinel image after cloud removal still have image attributes

The case of this tutorial mainly solves that after we process the function function, the image will lose its original properties. This time we use the sentinel-2 dataset, and the function here is to go to the cloud function.

question:

I'm new to the GEE platform and I'm doing a functional masking of a sentinel 2 image set and I keep getting an error when adding print data to see the metadata cloud overlay. I would like to know the set of images taken for the clouds. But it always shows the band image instead of the date cloud.

Please help me and confirm what I am doing wrong. thank you for your help! !

Original code:

var AOI = 
    /* color: #d63000 */
    /* displayProperties: [
      {
        "type": "rectangle"
      }
    ] */
    ee.Geometry.Polygon(
        [[[114.91370459315428, -3.519343796715037],
          [114.91370459315428, -3.544016090274636],
          [114.94391699549803, -3.544016090274636],
          [114.94391699549803, -3.519343796715037]]], null, false);

function maskS2clouds(image) {
