How do I delete a SG along with resources in it. (one command)

Hi

My intention is to remove a SG and it’s resources associated with that, but when I try hagrp delete <service group> it’s giving below warning, but same I could remove as a cluster admin account in GUI. Any difference between CLI and GUI?

hagrp -delete <SG name>
