Changing resolution on virtualbox mac

Supposedly the two commands you can use to change resolution are: VBoxManage setextradata "macOS 10.12 Sierra" VBoxInternal2/EfiGraphicsResolution 1920x1080 or VBoxManage setextradata "macOS 10.12 Sierra" VBoxInternal2/EfiGopMode 5. I have tried both and neither of them work. I am running mac os 10.12.6 and running virtualbox 5.2.4.
