-- Use one of the following lenses to modify other fields as desired:
--
-- * 'detTaskId' - The ID of the export task. Specifying a task ID filters the results to zero or one export tasks.
--
-- * 'detNextToken' - The token for the next set of items to return. (You received this token from a previous call.)
--
-- * 'detLimit' - The maximum number of items returned. If you don't specify a value, the default is up to 50 items.
--
-- * 'detStatusCode' - The status code of the export task. Specifying a status code filters the results to zero or more export tasks.
