iPhone iOS 18.6 Files app delete directories

I'm trying to connect to a samba share on a linux machine. And I keep failing. I get various errors. I've made several attempts using different paths on the linux machine. Now, my Files app > Connect to Server > paths has several paths that seem useless in it. I see no way to delete any of the different paths. There is the Remove option under the server's option, but that only deletes the server, not the several paths. For example, I tried connecting to

smb://myserver.net/share/samba

smb://myserver.net/shares

smb://myserver.net/samba

So if I connect to smb://myserver.net/home/user, I also see

share/samba

shares

samba

in the list of directories. How do I delete those directories

(share/samba

shares

samba) ?
