Media Skip back/forward via USB keyboard keys

I have an Android 14 phone (Samsung Galaxy A15). I want to control media playback with a USB keyboard connected to my phone. The keyboard does not have dedicated "media playback" buttons. Is there an app (or setting) that lets me do that? I tried the app Button Mapper (by flar2) and it works for play/pause, but not for skipping back/forward. Note that the media app I want to control is this one: [Music Player & MP3 Player by InShot Inc.](https://play.google.com/store/apps/details?id=musicplayer.musicapps.music.mp3player)
