How to hide the Intercom chat widget, and only chat window visible?

I’m currently using Intercoms live chat, as shown on this image I only want the chat window to be visible and hide or remove the chat button/widget.

I also checked their document and I didn’t find anything or maybe I just missed it.

<script>window.intercomSettings = {
  api_base: "https://api-iam.intercom.io",
  app_id: "yuow5buf",
};
</script>

<script>(function(){
  var w = window; 
  var ic = w.Intercom; 
  if (typeof ic === "function") {
    ic('reattach_activator'); 
    ic('update', w.intercomSettings);
  } else {
    var d = document; 
    var i = function() { i.c(arguments); }; 
    i.q = []; 
    i.c = function(args) { i.q.push(args); }; 
    w.Intercom = i; 
    var l = function() {
      var s = d.createElement('script');
      s.type = 'text/javascript'; 
      s.async = true; 
      s.src = 'https://widget.intercom.io/widget/yuow5buf'; 
      var x = d.getElementsByTagName('script')[0]; 
      x.parentNode.insertBefore(s, x);
    }; 
    if (document.readyState === 'complete') {
      l();
    } else if (w.attachEvent) {
      w.attachEvent('onload', l);
    } else {
      w.addEventListener('load', l, false);
    }
  }

  // Hide the chat button initially
  var intercomChatButton = document.querySelector('.intercom-launcher');
  if (intercomChatButton) {
    intercomChatButton.style.display = 'none';
  }

  // Observe changes to the chat window
  var observer = new MutationObserver(function() {
    var intercomChatWindow = document.querySelector('.intercom-messenger');
    if (intercomChatWindow && intercomChatWindow.style.display !== 'none') {
      intercomChatButton.style.display = 'none';
    } else {
      intercomChatButton.style.display = 'block';
    }
  });
  observer.observe(document.body, { childList: true, subtree: true });
})();
</script>

what I want to achieve is to make the chat window always visible no need any button/widget to open the chat.
And in case it doesn’t have an option or workaround for it, can you guys recommend a live chat that can it? I got stuck on this one, any help would be much appreciated!
