Hey @teamrappid — you can do this in the on-prem version of Retool in a roundabout way. When you deploy Retool on-prem, you control access to the database where users are stored. You can add this database as a resource in Retool and query it inside Retool apps to get the full list of users.
We don’t have great documentation on this, but if you want more information let me know and we can help!
