How can I create a listener for @discordjs/voice states?

const { VoiceConnectionStatus, AudioPlayerStatus } = require('@discordjs/voice');

connection.on(VoiceConnectionStatus.Ready, (oldState, newState) => {
    console.log('Connection is in the Ready state!');
});

player.on(AudioPlayerStatus.Playing, (oldState, newState) => {
    console.log('Audio player is in the Playing state!');
});
