Good Morning,
you can add in the iframe html and put as (error loading) and add a fixed button that shows and hides the iframe html, it will only take up space for click if it is being displayed.
example:
export function chatbuttom_click() {
//Add your code for this event here:
if ($w("#chatbox").collapsed) {
$w("#chatbox").expand();
} else {
$w("#chatbox").collapse();
}
}
(chat box) is the ID of the (iframe html)
