I am using “ogc/wms/” api and NDVI layer i am using
 

//VERSION=3

function setup() {

            { id: "dataMask", bands: 1 }
        ]
      };
}

    let val = index(samples.B08, samples.B04);
    let imgVals = null;

But i am unble to show image in the MAP with polygon data. I need to change my code.
Like attached the image
