  title: Auth0 Find User by Email and Assign Role
  summary: Look up a user by email and, when found, assign tenant roles to that user.
  description: >-
    A find-then-act access flow. The workflow searches for an existing user by
    email address and branches on the result: when a matching user is found it
    assigns the supplied tenant roles, and when no user matches it ends without
    making changes. Each step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
