Google API, when clicking on the map go to google map to the same location with a marker?

Question

Google Maps

The problem is that the task is with a custom marker, that is, I form the map with code

function drawMap(address, iconUrl){
  
  var firstLatlng = new google.maps.LatLng(42.3551142, -71.0594341);
  var firstOptions = {
      zoom: 19,
      center: firstLatlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP,
      disableDefaultUI: true,
      draggable: false,
    };

  window.map = new google.maps.Map(document.getElementById("contact-google_map"), firstOptions);
    
  geocoder = new google.maps.Geocoder();
    geocoder.geocode({'address': address}, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
      
      var markerLoc =  results[0].geometry.location;
      
            map.setCenter(results[0].geometry.location);
            var marker = new google.maps.Marker({
                map: map,
                position: results[0].geometry.location,                            
                draggable: false,
                icon: iconUrl
            });    
            
            var loc = 'https://www.google.com.ua/maps/@' + markerLoc.k +',' + markerLoc.B +',19z';
            
            google.maps.event.addListener(marker, 'click', function () {
                window.location.href = loc;
            }); 
            google.maps.event.addListener(map, 'click', function () {
                window.location.href = loc;
            }); 
        }
    });
}

I implemented the transition using .addListener, it works, but the transition does not have a marker, but it is needed.
Has anyone experienced this? How to implement?
