Does anyone know how to access Doom Beta console/shell?

I found this which might lead to unlocking advanced settings

Force the game settings to be visible

"shell_ForceShowGameSettings" Show the advanced settings button

"shell_ShowAdvancedSettings"

set to turn on the menu option to go to the DEV menu

"menu_showOptionForDevMenu"

if set will hide non-Snap menu options

"menu_snapDemo"
