The embedded chat window can be disabled directly in the Chatstack HTML code. You will need to update the following line from your step 1 Chatstack HTML code (as detailed at Documentation – Chatstack jQuery HTML Code):

LiveHelpSettings.embedded = true;

With the following with the value changed:

LiveHelpSettings.embedded = false;

Updating the above line from your step 1 Chatstack HTML code block will disable the embedded chat window shown on your page and will instead use a popup window as the default chat window.

If you are having difficulty disabling the embedded chat window, feel free to email us or request a chat when Chatstack is online.
