I want to enter commands in the console to achieve “immersive mode” functionality.
Change to full screen, as opposed to windowed.

I’m not sure, but I don’t think so, because the command line is not available in a packaged version.
Thank you very much.
To be clear: there is a command line node, but you can’t open the command line and type into it…
At last! I found a command that can be displayed in full screen(Immersive mode).
This command can toggles Immersive mode for the viewport.
LevelEditor.ToggleImmersive

This is the command to toggles Immersive mode for the viewport.
LevelEditor.ToggleImmersive
