@Cr4z33 if you don’t want to use gaction like me .
I’ll share my transcription hook and command i’m using with this module and others.
It works perfectly. with raspotify. raspotify is pretty easy to install and run.
transcriptionHook: {
        HIDE_ALL_MODULES: {
            pattern: "standby mode",
            command: "HIDEMODULES"

          STOP_PLAY: {
            pattern: "stop the video", // this is for youtube but it is preferable to have youtubeAutoplay: false, when running spotify so you don't get interaction with youtube player.
