Obtaining inverter coolant temperature via OBD

Has anyone had success with reading the Gen 5's inverter coolant temperature via OBD?

I've tried using both OBD Fusion and Car Scanner with a Bluetooth dongle to no avail. I've attached screenshots of all the temperature readings, but nothing related to the inverter is showing. As you can see, I've correctly selected the Prius Prime profile as well, so I'm not sure what else to try.

I'm stumped!
