Unable to use OpenLayers library in Browser Debugger Console (React JS)

问题

I am having one application which has OpenLayers Map and implemented using reactjs with OpenLayers library. I am trying to get the latitude and longitude of the map from the browser console in order to use the same in my selenium automation.

I am using the below code in the console and getting an error as below

Error:

"Uncaught TypeError: map.getLayers is not a function
    at <anonymous>:1:5"

Script:

   map.getLayers().forEach(function(layer){
    if(layer instanceof ol.layer.Vector){
      var features = layer.getSource().getFeatures();
      features.forEach(function(feature) {
        console.log("Features Coordinates from Main Class :"+ol.proj.toLonLat(feature.getGeometry().getCoordinates()));
     });
    }
  });

When I inspect OpenLayersMap and it has class name as map.So, I have used map.getLayers() in script.
