Cannot access NAS via SMB on COSMIC Atomic

When I attempt to access my Synology NAS via COSMIC Atomic, I can see the logo for it when I look in the Networks menu option in the sidebar, but if I click on the icon, it just takes me to an empty folder instead of asking me for my credentials to log in to the NAS for the first time. On KDE Plasma or GNOME, I am always greeted with a dialog box to enter my credentials and I’m good to go, but I don’t get such a dialog box on the COSMIC Atomic desktop.
