The documentation is wrong. There are three dots in the Wi-Fi settings menu near the close, minimize, maximize buttons. If you click that the "Connect to Hidden network" option is revealed.

When it comes to wifi - I'm equal to an idiot. I tried to follow https://help.ubuntu.com/stable/ubuntu-help/net-wireless-hidden.html.en but I could not find any "Connect to Hidden Wifi" option following instructions. I did this first on a sony ultrabook & failed, now on a thinkpad sl510. Problem I believe is either 19.04 doesn't match docs, or idiot-at-keyboard.
