Get a list of connected desktop (or mobile) clients per server / device / user

How can one get a list of ‘authorised desktop clients’ per user ?
For example : User’s laptop is loaded with desktop client and
desktop computer and
mobile phone.
And the ‘last seen’ for each such device.
(last seen as per the occ command seems to only track browser logins)
I need to know what desktop (or mobile) clients are currently logged on or at least active on the server. (50 user)

I’ll rephrase the question. How can I get the Devices and Sessions list per user in a list for all users ?
(as per the example)

I haven’t seen this option and no feature request for it. You can probably check manually the session-table in the database.
This could be an idea for an app…
