The create_user() function allows you to create a user on a local Hue
network, but it requires pressing the button on the Hue bridge then
executing this command within 30 seconds. delete_user() is not implemented
because, apparently, it can only be executed through remote authentication.
create_user(devicetype)a string naming your app and the device it's running on;
suggested format: <application_name>#<devicename> (e.g. Hue#iPhone13).
Returns a list with the newly created username and clientkey
