. It is Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://supervisor.ext-twitch.tv’) does not match the recipient window’s origin

I have tried to display it on the website, the website can be displayed correctly,

So the extension works as expected when testing in a panel?
