How can I give *exclusive* access to another user/guest/family member of a camera? Possible?

I’d like to add a 2C camera to my homebase that only ONE guest/family member has access to - so that means I don’t have access to it.

Is that possible?

I tried adding registering them directly to the homebase but that knocked out all the devices I had access to on the same homebase.
I can set them up as a guest/family member etc but that means I still have access to the camera.

The situation is I need to give one of my daughters a camera in their room so they can monitor the (repeated) intrusions of a sibling… But naturally, they would prefer if I had no access to that camera.

Hoping someone can help… Thanks.
