How can I make sure Superusers only see their own sessions?

You can now choose if Super users can see each other's sessions.

The subscription owner can choose if superusers can see all sessions, or only the one the have created.

They can find this option by going to the Admin section of the platform and then click 'Superusers Will See All Sessions.'

Here you find the option to give them access to all sessions or to toggle it off, so they can only see the sessions they created or are added to.

You can see here how to do that.
