Resetting quest floor level on HMDMounted

I am developing an AR application with Unity using the Meta SDK v83
Every time I take of the headset the floor level just shoots up or down when I put it back on. To fix it either I have to:

• Restart the app
• Go to settings >> Environment Setup >> Boundary >> Set floor level (sets it back to the correct height without my input)

But that is not very user friendly. I'd like to have the quest recalculate floor level automatically when one of these events is fired:
OVRManager.HMDMounted
OVRManager.TrackingAcquired

There does not seem to be a straightforward way to do exactly what set floor level does in settings.
