I recently made a discord word filter bot and I was wondering how I could make it configurable per server? I want to be able to make a command that adds words to be filtered to the code and I want people to be able to add a custom prefix per server. I also want people to be able to set their log channel per server. Can someone help me with this please? I spent a lot of time on this bot and I dont want to just keep making more of the same bot for different servers. I'm using discord.js 12.5.3. I'll attach my code below.

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

client.once('ready', async () => {
console.log('yay, the bot is online')
client.user.setActivity('im real', {type: 'PLAYING'})
})

client.on('message', async message => {
if(message.channel.type === 'dm' || message.author.bot) return;

const logChannel = client.channels.cache.find(channel => channel.id === '921730444498726924')
let words = [“bad”, “words”, “here”]

let foundInText = false;
for (var i in words) {
    if (message.content.toLowerCase().includes(words[i].toLowerCase())) foundInText = true;
}

if (foundInText) {
    let logEmbed = new Discord.MessageEmbed()
    .setDescription(<@${message.author.id}> Said a bad word)
    .addField('The Message', message.content)
    .setColor('RANDOM')
    .setTimestamp()
    logChannel.send(logEmbed)

    let embed = new Discord.MessageEmbed()
    .setDescription('That word is not allowed here')
    .setColor('RANDOM')
    .setTimestamp()
    let msg = await message.channel.send(embed);
    message.delete()
    msg.delete({timeout: '3500'})
}
})

I've tried following a tutorial but it didn't help because I need one specifically for my case. If anyone could help, that would be great.
