// get the track info using get state
await CodyMusic.getRunningTrack().then((track: Track) => {
    // returns the Track data
});

// play a specific spotify track
await CodyMusic.playTrack(
    "spotify",
    "spotify:track:2YarjDYjBJuH63dUIh9OWv"
).then((result) => {
    // track is playing

// handling errors
await CodyMusic.playTrack("spotify", 1000000000).then((result) => {
    // result will contain the "error" attribute with the error message
    if (result.error) {
        console.log(`Unable to play track, error: ${result.error}`);
    }
});
await CodyMusic.getRunningTrack().then((result) => {
    // result will be the best effort track that is playing.
    // i.e. if you have your itunes app running, it would show you that track
