I want to display the updating count of vehicles on a particular road in my google maps w.r.t to a marker I have placed.I am using the MongoDB database from which I retrieve the count value and want to display this real time count in my map. Is there any solution to display this continuously changing data in the map?
Thank you.

What I have tried:

      var map;
      function initMap() {
        
        map = new google.maps.Map(document.getElementById('map'), {
			center: {lat: 9.385751738316223, lng: 76.57526832439837},
	
          zoom: 13
        });
		
		var trafficLayer = new google.maps.TrafficLayer();

   function addMarker(property){

           {{#each data}} // I get this data from index.js
              contentString =  {{this.Count}}                              
            {{/each}}
            var detailWindow = new google.maps.InfoWindow({
               content:contentString});
           
            marker.addListener("click", ()=>{
                   detailWindow.open(map, marker);
                   
             })
