Currently, if a user owns a row in the database you cannot expand to the user.
Though you could draw a line from the user type to the entity you want to expand to this duplicates the field data, making it technically not 3NF
Exposing in the GQL and most likely rest endpoint, would allow for the developer to get all the users information when accessing the root entity. one example of this is a comment system where any users
type can make a comment, Should you want to display the user’s full name in the UI you would either need to draw the ownership reference on the model or create custom expand code to do this which could be used as the basis of the bot implementation
