              Filter args:
  
              pattern (Optional[str]): a pattern to filter workers
                  ex.: '^dispatch|^email' to filter names starting with that
                        or 'dispatch.*123456' to filter that exact name and number
                        or even '123456' to filter that exact number anywhere.
              negate (bool): if True, finds tasks that do not match criteria
  
              Display args:
  
              stats (bool): if True shows worker stats
