Back-UPS Power Shutdown Protocol With Power Outage

I have connected an APC UPS 600 VA / 330 WATTS to my iMac which is running Mojave 10.14.6. Unfortunately, PowerChurte has been discontinued for macOS.

"Mac OS X contains built in, basic support for an APC UPS..."

I found the the following regarding macOS native power management.

I have followed the directions below, but there are no UPS Options of any kind anywhere as shown below. Any suggestions?

Thanks!
