Xcode on two monitors

I have been unable to find any way to detach the inspector pane of Xcode (13.2.1) so it can be displayed on a second monitor. I can open individual class files and display them on a second monitor (and that is a help and that is a big help in setting up nib files) but can find no way to separate the inspector pane from the main Xcode window so as to drag it to the second monitor. From doing some online searching it seems that this was possible earlier, but I can not see any way to do it.

Is it possible? And, if so, how?
