Exit full screen mode in Mac?

Is it possible to run the Mac app in a window? I searched the archive and saw posts about a window mode check box in settings, I don’t have that.

That’s in the Windows app, where you have to restart the app for the setting to take effect so much less convenient. On Mac it’s the same as all normal apps, just click on the green circle to toggle full screen mode, point mouse to the top left corner for it to appear if necessary.
