Doesn't work for me about discord-anti-spam HOT 1 CLOSED

const Discord = require("discord.js");
const client = new Discord.Client();

const antispam = require('discord-anti-spam');

antispam(client, {
  warnBuffer: 3, //Maximum amount of messages allowed to send in the interval time before getting warned.
  maxBuffer: 5, // Maximum amount of messages allowed to send in the interval time before getting banned.
  interval: 1000, // Amount of time in ms users can send a maximum of the maxBuffer variable before getting banned.
  warningMessage: "stop spamming or I'll whack your head off.", // Warning message send to the user indicating they are going to fast.
  banMessage: "has been banned for spamming, anyone else?", // Ban message, always tags the banned user in front of it.
  maxDuplicatesWarning: 7,// Maximum amount of duplicate messages a user can send in a timespan before getting warned
  maxDuplicatesBan: 10, // Maximum amount of duplicate messages a user can send in a timespan before getting banned
  deleteMessagesAfterBanForPastDays: 7 // Delete the spammed messages after banning for the past x days.
  exemptRoles: ["Admin", "Chat Moderator"] // The names of the roles which should not be spam-filtered
  exemptUsers: ["user#1234"] // The Discord tags of the users who should not be spam-filtered
});

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

client.on('message', msg => {
  if (msg.content === 'ping') {
    msg.reply('Pong!');
  }
});

client.login('token');
