Google Home integration + Zooz Zen32

I have a Hubitat C5, running the newest software (2.2.8). I am using the built in Google Home app to share my zwave devices with Google Home. Everything works as expected, except my Zooz Zen32 app. It does correctly detect the local load relay as a standard switch, however it always reports "offline" to Google. I cannot turn the light on or off, or see its current status from my Google dashboard on my phone. Everything appears totally fine in my Hubitat dashboard, so I don't think this is a polling issue. Anybody else run into this?
