Is it possible to create a Super Admin API user without entering the Dashboard? I want to write a script that sets up a Listmonk instance and configures everything automatically so that it's ready to handle API calls. I know that you can do that with the "normal" (dashboard) Super User by providing LISTMONK_ADMIN_USER and LISTMONK_ADMIN_PASSWORD to the config. I was wondering if something similar is possible for API user.
