Cloudflare Access Argo Tunnel SMB Mac OS

Been following this guide:

The Argo tunnel seems to be up and the server is responding via TCP on port 445 via testing on Mac OS Terminal. Can’t figure out how to mount the share using Mac OS GUI. Finder – Go menu – Connect to server.

Tried every connection way I can think of, none seems to work.Anybody have this working or some ideas on what we might be doing wrong?
