Note: All the User Management API's have the endpoint: /graphql

Creates a self-service user for the same client (entity) as the logged-in user. The email is used as the username, a temporary password is emailed to the new user, and they must reset it after the first login. Returns the id of the new user.

Rules:

• The enable-managing-ssu-by-ssu global configuration must be enabled.
• The logged-in user must be linked to exactly one client, and that client must be an entity (not an individual).
• At least one role is required, and every role must be a self-service role. Use Get User Template or Get Self-Service Roles to look up role ids.
