How to load the chat application in an iframe without using the <iframe> tag?

Question

I am trying to make a multi tenant Chatbot application using microsoft's Bot Framework webchat, So I want my clients to include this kind of code which I think is standard for such applications:

<script src="link to the cdn" ></script> 
<script> 
    BotfuelWebChat.init({ appToken: '444107', 
    size: { width: 500, height: 600 }, 
    startOpen: false,
    startFullScreen: false, 
      theme: { colors: { background: '#faf3db', main: '#244891', 
      primary: '#0084f4' }, layout: { compact: false, rounded: false, 
      shadowed: false, noHeader: false, noBorder: false, 
      noHelpMessage: false } } }); 
</script>

Now my question is what javascript or jquery code should be written in the CDN included above such that my application gets loaded in the chatbox of the client.

I am using Node.js for backend of the application.

Just for your reference, and for more the details your requirements, I think you should implememnt yourself.

var BotfuelWebChat = {
    init:(options)=>{
        const params = BotChat.queryParams(location.search);
        var div = document.createElement('div');
        div.id='bot';
        div.style.width =options.size.width+"px";
        div.style.height =options.size.height+"px";
        div.style.position ="relative";
        document.body.appendChild(div);

        BotChat.App({
              bot: {id: 'botid'},
              locale: params['locale'],
              resize: 'detect',
              user: {id:'userid'},
              directLine: {
                secret: options.appSecret,
                token: options.appToken
              }
            }, div);
        }
}

And in your html script:

<script>

    BotfuelWebChat.init({
      appToken:'directline secret',
      size: { width: 500, height: 600 }
      })
    </script>
