Nextcloud Box External Storage unable to configure

Hi all.

I’m working through my issues, so far so good, but now I am trying to set up External Storage. The files I was to provide access to are on an iSCSI Raid, but I am going to use a workstation running the client to make them available. When I am logged into the Nextcloud Box server as the Admin, and I attempt to change the user I set up for this, I do not see anywhere an option for External Storage. I have enabled the module, but even in my own Personal Settings I see no place to add external storage.

I guess I also had to add External User Support. Still don’t see where to configure External Storage for a user as an administrator.

NVM I found it. But now I see I do not have smbclient installed. It is not visible in installed or not installed. Is it a downloadable module??
