Cannot write ISO with Gnome Disks (CD/DVD drive grayed out)

[Kafui Odzangba Dake]

After inserting blank DVD+RW and choosing "Open with Disk Image Writer" in the ISO file right-click menu

What I expected:
CD/DVD drive should be "selectable" in the gnome-disks Restore Disk Image dialog.

What I got instead:
CD/DVD drive is grayed out and cannot be selected. Same results if I run gnome-disks --restore-disk-image on the terminal.

Screenshot attached
