      Example:
      If the function is called and the server is started, it would create the following API endpoints:
      - GET /item/<string:name> which requires JWT authentication and returns the item if found, otherwise returns 404.
      - POST /item/<string:name> which creates a new item with a given name and returns it with status code 201.
      - GET /items which returns a list of all items.
