That should mean two things:

That probably means two things:
  1) you don't have the most recent LaTeX.  The 2020-06-01 release has
     |\NewDocumentCommand| built-in, so it should not be undefined.
  2) you don't have the |l3packages| CTAN package (which contains
     |xparse.sty|, which defined |\NewDocumentCommand| until recently).

Either updating or installing |l3packages| should fix the problem.
