NEC 400.7 the 11 listed uses for flexible cable. This is definitely a code violation. Item 11 in the list is the one you want

  1. Between an existing receptacle outlet and an inlet, where the inlet provides power to an additional single receptacle outlet. The wiring interconnecting the inlet to the single receptacle outlet shall be a Chapter 3 wiring method. The inlet, receptacle outlet, and Chapter 3 wiring method, including the flexible cord and fittings, shall be a listed assembly specific for this application.

Well, good on you for actually providing the ref. It's actually 400.10 now as of 2023 but the wording is basically the same.
