You need to make sure that both computers are not only on the same WiFi network, but also that each designates that network as Private.
Settings, Network & Internet, WiFi Pane, then activate the button that is your network name. In the dialog that comes up, under the Network Profile section make sure that the radio button for Private is selected on each machine. That automatically configures the firewall such that the two machines can see each other (they're discoverable) when connected to that network.
If Public is chosen the machine will do its best to wall itself off from all other machines on that network.
