Is there a way to log out all devices from your Surfshark account?

Hi, as the question states: my cousin is borrowing my Surfshark VPN account for a few weeks for a trip, but I was wondering if there was any way for me to log out all his devices myself (its fine if mine get log out too, as I can log back in once I reset my password later) once he’s back? I am quite a new user of Surfshark so apologies if the feature exists in the settings menu and I just haven’t found it yet.
