How to disable and hide the navbar and statusbar on MC18?



As I understand it should be possible to completely disable and hide both the statusbar and navbar when running on Android on the MC18. However, I can't find any documentation on how to do this and when I Google I found this; Toggling MC18 Navigation (and Status) Bar visible state  · Pietro F. Maggi, but this doesn't seem to have any effect.


Can you please enlighten me on if this is feasible or not and if so, how to do it correctly?
