I have a CEP extension in After Effects and I want it so that when a user clicks a button, a settings dialog opens up in a new floating dialog box. Seems like it would be such basic functionality but somehow I'm not seeing anywhere in the (admittedly sparse) documentation how to open up a dialog box. I've seen some other people say that you can make a hidden extension which opens the dialog, but I've seen no example of that and it is unclear how that would work to me.
