How to use "guiAttachToDirect"

[Dealman]

So as of lately I've been playing around with DXGui for a while, and I absolutely love the looks of it, however, it's missing some of the elements needed to make a truly useful GUI, such as EditFields and GridLists.

However, I stumbled upon a picture of some kind of Vehicle Spawner script(Believe it was done by the one and only Solidsnake14), which was using DXGui but had regular GUI elements attached to it and I then managed to find this; guiAttachToDirectX

However, I haven't been able to make use of it, I always seem to mess it up. I managed to get it to return no error or warnings, but the GUI Element still didn't show up.

Does anyone have any example of how to properly use this function?
