I want to execute a piece of code when the window of my panel extension is closed. I know that chrome.windows.onRemoved.addListener is the function I'm Looking for but by default it accepts only ["normal", "popup"] window_types (see attached screenshot) or click on this link https://developer.chrome.com/docs/extensions/reference/windows/

How do I format the filter object so that it accepts panel type windows? Thank you for your time :)
