We have a collaboration set up between our 10.6.1 portal and ArcGIS Online for which I want to delete a workspace entirely. I've deleted the workspace from the ArcGIS Online (host) and have left the workspace in the portal (guest) but there isn't a workspace deletion option in portal. The only action available from the cog is the join the workspace.
Could this be what "Remove Portal Group Link" in the portal directory is for (see attached)? I appreciate any help.
