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

Replaces the roles of another self-service user of the same client. Returns the id of the updated user.

Rules:

• The enable-managing-ssu-by-ssu global configuration must be enabled.
• You cannot update your own user.
• The logged-in user and the user being updated must both be linked to the same single client, and that client must be an entity.
• At least one role is required, and every role must be a self-service role.
