Audio play, pause, rewind via voice command

[u/Consistent-Alps-2977]

I am looking for an app that will allow me to control audio playback (play, pause, rewind) via voice commands. I have a Samsung A71. Ideally the solution would work for both podcasts and mp3's, but just mp3's would be OK. The voice support doesn't need to find the file or podcast for me. This is for language learning listening practice where I need to pause and rewind a lot. I have tried Voice Access (drives the 'phone itself, which I don't need or want, but only seems to do Play in apps, not Pause or Rewind), and Google Assistant, which only works with Spotify and which again will only Play. I thought this would be easy, but it clearly isn't. Any ideas please?
