Issue requesting group-associated geofences via API

I have a user (non-admin) which i use for api access only.
This user is part of a group

That group has geofences associated

Now using Basic Auth with that user account i am trying to get a list of geofences like so

/api/geofences

I also tried

/api/geofences?groupId={Id of the group}

But the list returned is empty.
(Requesting devices, groups, etc, works just fine)

How does this work using this API?

Group only controls device permissions. It doesn't give access to anything else.

Okay.

Thank your for the response.
