NVidia AR Tracker Body found as modifier

Hello everyone,
is there a way to use the Nvidia AR Body tracker to check for the presence of a person in front of the camera. I tried using the Extractor modifier, and i can see the “body found” in the Source Envelope, but it only sets the value to 1 and when there is no person in the camera view it still stays at a value of 1 instead of going to 0.

Any ideas on how to go about doing something like that?

It looks like there is an issue with that property - I’ve passed it over to the dev team to look into.
