Wher can I find the trigger of Double click title bar to max/restore window?

Thanks, I just want to make sure if it still existed or removed, or if any plan to add this in the future?

Thank you very much.

That's in the "Other" tab in BTT.

Thanks, I found this trigger in Other tabs, but maybe I didn't make the question clearly, it's not trigger of double click title, I want action of "Double click window title".

My requirement is touchbar button click, max or resume window size. That can be realized?
