I'm building a discord bot and when I try to make it play music in the voice channel, it just doesn't work. Is the dispatcher const and/or connection.play() part of some library? I'm currently using discord.js v12 and following their guide available here: https://v12.discordjs.guide/voice/

Note = I have @discordjs/opus installed, as well as FFmpeg, however, I don't require FFmpeg in my code and I don't know if I should. For that matter, I also don't see where I should use the opus library in my code.

The part that I get an error from my code is as follows:

pathMusic = musicTitle + '.mp3';

const dispatcher = connection.play(pathMusic);

dispatcher.on('start', () => {
    console.log(musicurl + ' is now playing!');
    msg.channel.send('Now playing: ' + musicTitle);
});

dispatcher.on('finish', () => {
    console.log(musicTitle + ' has finished playing!');
});

dispatcher.on('error', console.error);

msg.channel.send('Now playing: ' + musicTitle);

Any help would be deeply appreciated!
