myMap is there a way to authenticate

Question

Is there a way to able to get the data even it was restricted sharing. I'm currently using mymap.

var  src = "https://www.google.com/maps/d/kml?mid={id}&forcekml=1"

geoXml = new geoXML3.parser({
      map: map,
      infoWindow: infowindow,
      singleInfoWindow: true,
      afterParse: useTheData
     });
     geoXml.parse(src);
      
     function useTheData(doc) {
      var geoXmlDoc = doc[0];
      console.log(geoXmlDoc)
    } 

My error is cors.
