Lock presence automation advice

Hi all. Just bought my first hub…V3. I am very new to this technology. I have fitted a Danalock V3 to my front door but couldn’t get it to lock/unlock with geofencing so installed the classic app. Tried it last night to unlock as I returned home and it seemed to work fine. My question is…when I’m setting up the goodbye automation and I select the automatically perform function and then everybody leaves, does this mean that all the members of the house need to have left the geofence radius in order for the lock to operate. Please excuse my ignorance. Thanks in advance.
