How can I modify this script to work with a 3d object like a cube to open a link in a new tab bypassing popup blockers?

Hi, I used this small piece of javascript code to open external links in an old project, but had to instruct the users to allow popup windows to make it work: var setURL : String = "http://www.google.com";

 function OnMouseDown():void {
     Application.ExternalEval("window.open('" + setURL + "')");
 }

Now I'm trying to make use of the example provided in [https://github.com/valyard/UnityWebGLOpenLink][1]

This are the 3 main files used by this example:

1. Plugin:

   var OpenWindowPlugin = { openWindow: function(link) { var url = Pointer_stringify(link); document.onmouseup = function() { window.open(url); document.onmouseup = null; } } };

   mergeInto(LibraryManager.library, OpenWindowPlugin);

2. Script 1:

   using UnityEngine; using System.Runtime.InteropServices;

   public class Link : MonoBehaviour { public void OpenLinkJSPlugin() { #if !UNITY_EDITOR openWindow("http://unity3d.com"); #endif }

     [DllImport("__Internal")]
        private static extern void openWindow(string url);
    }
   
   
   

3. Script 2:

   using UnityEngine; using UnityEngine.EventSystems; using System; using UnityEngine.Events;

   public class PressHandler : MonoBehaviour, IPointerDownHandler { [Serializable] public class ButtonPressEvent : UnityEvent { }

     public ButtonPressEvent OnPress = new ButtonPressEvent();
    
        public void OnPointerDown(PointerEventData eventData)   {
            OnPress.Invoke();
        }
    }
   
   
   

This example is for making buttons open external links, but I need to transform it in someway that I can attach it to a 3d object like a cube, where I can define the URL to be opened for each element, and make the call to the plugin when the player clicks on the cube.

Thanks in advance for any help!
