Once the second router booted, the light turned magenta. I connected a cable directly from the existing router’s LAN output into the WAN input of the new router. Nothing else is connected to the new router in AP mode. So, it now has internet connectivity, and the
AttachedDevices screen of the first router’s admin page shows the new router just like any other device. And, the second router is broadcasting the new differently-named WIFI network as I verified by my phone, connecting to it and visiting the internet. I also updated the firmware to the latest just to eliminate any ghost problems. Things continue to work.

Found it useful to use the same SSID & wireless password as my main router But gave it a different name (i.e. RBR50B). It shows up on my main router as still RBR50 (e.g. at http://192.168.1.43)
