This is easy to solve.
Display Settings and WiFi Settings launch on the physical Helioclock display screen, not in your remote browser. When you click those buttons, the GNOME settings panel opens on whichever monitor is connected directly to your Pi. You need to be in front of that screen to see and use them.
If you want to change WiFi settings, that has to be done from the unit itself with a keyboard and mouse connected. No, we can’t make this a feature.
