我尝试引用客户端使用discord.js发送的上一条消息
我该怎么把最后一条信息发送出去呢？

client.on("messageCreate", (message) => {

    if (!message.content.startsWith(prefix) || message.author.bot) return;

    const args = message.content.slice(prefix.length).split(/ +/);
    const command = args.shift().toLowerCase();

    if (command === 'set-reminder'){
        channelName = client.channels.cache.find(channel => channel.name === "spam");

        message.channel.send("Command Works"); 
        channelName.messages.fetch({ limit: 1 }).then(messages => {
    // find "command works" message (previous message from client)
           let lastMessage = messages.first();
          
           console.log(lastMessage.content);
        })
    }
})```
