how to create multi container in konva js?

I want to be able to create multiple container. For example, by clicking a button in a new tab, a new container will be created with a new ID and the ability to draw a shape in it.

<html>
  <head>
    <script src="https://unpkg.com/konva@8.3.12/konva.min.js"></script>
    <meta charset="utf-8" />
    <title>Konva</title>
      <link rel="stylesheet" href="//code.jquery.com/ui/1.13.2/themes/base/jquery-ui.css">
  <link rel="stylesheet" href="/resources/demos/style.css">
    <style>
      body {
        margin: 0;
        padding: 0;
        overflow: hidden;
        background-color: #f0f0f0;
      }
    </style>
  </head>
  <body>
  <button id="add-container">Add Container</button>
  <div id="tabs">
  <ul>
    <li><a href="#tabs-1">container</a></li>
  </ul>
  <div id="tabs-1">
<div id="container"></div>
  </div>
</div>
    
    
      <script src="https://code.jquery.com/jquery-3.6.0.js"></script>
  <script src="https://code.jquery.com/ui/1.13.2/jquery-ui.js"></script>
    <script>
      var width = window.innerWidth;
      var height = window.innerHeight;

      var stage = new Konva.Stage({
        container: 'container',
        width: width,
        height: height,
      });

      var layer = new Konva.Layer();

      var circle = new Konva.Circle({
        x: stage.width() / 2,
        y: stage.height() / 2,
        radius: 70,
        fill: 'red',
        stroke: 'black',
        strokeWidth: 4,
      });

      // add the shape to the layer
      layer.add(circle);

      // add the layer to the stage
      stage.add(layer);
      
        $( function() {
    $( "#tabs" ).tabs();
  } );
  var count = 0
  $("#add-container").click(()=>{
        $(`<li><a href='#cnt-${count}'>Container-${count}</a></li>`)
    .appendTo("#tabs ul");
    $(`<div id='cnt-${count}'>Container-${count}</div>`).appendTo("#tabs");
    $("#tabs").tabs("refresh");
    
    count++
  })
    </script>
  </body>
</html>

Something like this. But there must be the ability to draw shapes in each container, for example by using drag and drop in each container. I did this in my project but I can't figure out which container they should be drawn in. Can you think of a solution?
