Full Screen Xterm Window?

[Atod Notbora]

When using XQuartz on MacOS is there a way to make an xterm window
completely full screen, without the top title bar or dock below?  Like a
terminal?

At the moment, it appears my XQuartz session uses an Aqua style
WM.  I'm wondering if that has something to do with the full screen
mode.  I also enter full screen by right clicking on Xterm and clicking
on full screen.

Thanks
