How to bind Image on an external server in Project Tiny(pure ECS,DOTS)?

I have an image file that I have uploaded to an external server.

I want to specify this image with a URL and bind it as a texture for a 3D object in the game.

I was able to open it as a separate tab with the following code, but I don't know how to get the object to bind to from the javascript side.

I have a Quad object named UrlLoader on the Unity side and want to bind it as a texture for that object. There is no problem even if you attach Generate Authoring Component to Quad.

 mergeInto(LibraryManager.library, {
     OpenURL: function (url) { 
         url = UTF8ToString(url);  
         var gameCanvas = document.getElementById("UT_CANVAS");  
 
         if (gameCanvas != null)  {
             var endInteractFunction = function()
             {    
                 window.open(url, "_blank");
                 gameCanvas.onmouseup = null;  
                 gameCanvas.ontouchend = null;              
             }
 
             gameCanvas.ontouchend = endInteractFunction;
             gameCanvas.onmouseup = endInteractFunction;
         } else {
             console.error("UT_CANVAS not found, was it renamed?");
         }
     });

What kind of code can be used instead of the code below?What should I do on the Unity side and Script side?

 window.open(url, "_blank");
