How do I use OVROverlay for stereo 360 video on Oculus Go?

I've been scouring the web for info on this. I got the Stereo180Video scene in the Sample Framework working on my Oculus Go following the steps outlined here. I tried working my way from there to a 360 scene but couldn't get it to play in 360 on my Go. It kept projecting it to a 180 surface in the headset. Does a similar example scene exist somewhere for how to set up a Stereo 360 OVROverlay for the Go?
