Razor Sila SSID when setting up a mesh network

Hi All, I am considering buying another Razor Sila gaming router but was not able to find an answer to the below question via the Sila Support FAQ page. Does a mesh network exist under one SSID, or does each additional gaming router in a mesh network each have a separate SSID? I assume a mesh network should exist under one SSID otherwise connected devices would have to manually jump between SSIDs depending on the signal strength which could cause latency/dropped connection. Thanks for your help.
