Katalon browser add-on - embed window into browser


For many years I’m using the old Selenium IDE browser add-on, whose window was nicely attached within the browser window itself. Perfect for executing multiple tests among as many different browser sessions on one device. There is also an option to ‘detach’ the addon’s window i.e. make it a separate one from the browser’s window, but I’m not fine with that.
And that’s the problem with Katalon… I only get the option to run it in a separate window which drives me nuts for many reasons. Would you kindly tell me if I’m missing something ? Is there a way to ‘embed’ the katalon recorder addon’s window within the browser window itself, just like with the old Selenium IDE addon ?

Thank you in advance.
