如何在Discord.js中删除收集器？

const { Client, Intents } = require('discord.js');
const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] });

client.once('ready', () => {
    console.log(`Logged in as ${client.user.tag}!`);
});

client.on('messageCreate', async message => {
    if (message.content === '!startcollector') {
        // 创建一个收集器，收集用户在10秒内发送的消息
        const collector = message.channel.createMessageCollector({ time: 10000 });

        collector.on('collect', collectedMessage => {
            console.log(`Collected ${collectedMessage.content}`);
        });

        collector.on('end', collected => {
            console.log(`Collector ended, collected ${collected.size} items`);
            // 收集器结束时，它会自动停止，但你可以显式调用stop()
            collector.stop();
        });
    }
});

client.login('your-token-goes-here');

collector.on('end', collected => {
    console.log(`Collector ended, collected ${collected.size} items`);
    collector.stop();
    // 删除对收集器的引用
    delete collector;
});
