discord - What's the prefix for mute

Question

Problems with my bot. Can't get mute to work. Help? Can't find any prefix and don't know where to add it or how to format it. I linked most of code below. Anti-spam and kick/ban works. New to coding to any help would be nice. Tips how set a general prefix for all code foward? Role is named mute and bot has all premissons it shall need to kick

const fs = require('fs');
module.exports = class mute {
    constructor(){
        this.name = 'mute',
        this.alias = ['tempmute'],
        this.usage = 'mute';
    }

    run(bot, message, args){
        let member = message.mentions.members.first();

        var command = args[0];
        var mentioned = args[1];

        var days = parseInt(args[3]);
        var hours = parseInt(args[4]);
        var seconds = parseInt(args[5]);

        if (message.member.hasPermission('MANAGE_ROLES')) {

        let muterole = message.guild.roles.find(role => role.name === "Muted");

        if (!message.guild) {
        if (message.guild.id === '505872328538718233') {
            let memberrole = message.guild.roles.find("name", "Member");
            member.removeRole(memberrole);

        }}

        let usermsg = new Discord.RichEmbed();

        usermsg.setTitle('You have been Muted.');
        usermsg.setColor('76b3fc');
        usermsg.setFooter('Please do not attempt to bypass');
        usermsg.addField('Muted by:',
        `<@${message.author.id}>`);
        
        let mutedmsg = new Discord.RichEmbed();
    
        mutedmsg.setTitle('User has been Muted Successfully');
        mutedmsg.setColor('76b3fc');
        mutedmsg.setDescription(`User muted: ${mentioned}
Muted by: <@${message.author.id}>
Reason: ${input}`);
        mutedmsg.setFooter('This mute has been logged.');

        if (message.content === `${command}`) {
            return message.channel.send('You did not provide a member to mute.');
        }
        
        if (message.content === `${command} ${mentioned}`) {
        return message.channel.send('Please input a reason for the mute.');
        }

You seem to have a lot, and I mean A LOT of outdated methods from Discord.js v11.

I'd highly recommend installing the newest version of DJS and reading all of the v12 changes that can be found here: https://github.com/discordjs/discord.js/releases/tag/12.0.0

Some examples:

• Discord.RichEmbed() no longer exists -> Use Discord.MessageEmbed()
• .addRole() no longer exists -> Use message.member.roles.add()
• .removeRole() no longer exists -> Use message.member.roles.remove()
