Include Last session in the List Users API

It would be very useful for us to have “last seen” (or last activity) of the user provided by the api on /users endpoint.

To mitigate this, we are currently fetching list of users and then for each user we call user session endpoint which is far from ideal. We would also face some timeouts from time to time and is overall very flaky.

Is there are way to obtain last session (only datetime) in the users list?
