-- | Creates a value of 'GetResource' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'grEmbed' - A query parameter to retrieve the specified resources embedded in the returned 'Resource' representation in the response. This @embed@ parameter value is a list of comma-separated strings. Currently, the request supports only retrieval of the embedded 'Method' resources this way. The query parameter value must be a single-valued list and contain the @"methods"@ string. For example, @GET /restapis/{restapi_id}/resources/{resource_id}?embed=methods@ .
--
-- * 'grRestAPIId' - [Required] The string identifier of the associated 'RestApi' .
--
-- * 'grResourceId' - [Required] The identifier for the 'Resource' resource.
