      summary: Set a profile field for a user.
      description: |-
        Set or update a profile field for a user. Must be authenticated with an
        access token authorised to make changes. Servers MAY impose size limits
        on individual fields, and the total profile MUST be under 64 KiB.

        Servers MAY reject `null` values. Servers that accept `null` values SHOULD store
        them rather than treating `null` as a deletion request. Clients that want to delete a
        field, including its key and value, SHOULD use the `DELETE` endpoint instead.
