vCAC 6 - how to attach a CD-ROM in virtual console?

Hi all, (me again).

I've created a Basic Bluprint to create an empty VM. I've add the property "VirtualMachine.CDROM.Attach" to true (screenshot attached), but when I open the console the only two options are "Send CTRL+ALT+DEL" and "Toggle Full Screen" (screenshot attached).

How do I attach a CD-ROM in order to install an operating system or any other application?

Thanks a lot,

D.
