Can'y see my Xiaomi Aqara Motion Sensor in Google Home

I have managed to pair my Xiaomi Aqara Motion Sensor with smartthings v3 hub using a custom DH and most devices I add this way also show up in my Google Home app except the Xiaomi Aqara Motion Sensor. Anyone know if this can be done and how?

As far as I am aware it can’t yet be done. I certainly don’t see my motion sensors.

Even my contact and temperature sensors are barely acknowledged by the Google Home app, even though the Assistant can report the readings.
