更改 config.js 文件中的值

如何解决更改 config.js 文件中的值

我想更改我的 Mercerxrd.js 配置文件中 conf.perms.commands 的值，如下面的命令所示， 请帮助我如何做到这一点（：

const conf = require("../../mercyxrd.js")
const discord = require('discord.js')
const fs = require('fs');
class roller extends Command {
    constructor(client) {
        super(client,{
            name: "roles",aliases: ["roles"],usage: "roles",description: "bu komut hakkında bilgi bulunmuyor."
        });
    }
async run(message,args,perm) {
    if(message.author.id !== "411621794131476480") return
    let embed = new discord.MessageEmbed()
    if(!args[0]) return message.channel.send(embed.setDescription(`specify an argument`))

    if(args[0] == "register-auth") {
    let rol = message.mentions.roles.first() || message.guild.roles.cache.get(args.splice(1)[0]) || message.guild.roles.cache.find(r=>r.name===args.splice(1).join(''));
    if(!rol) return message.channel.send(embed.setDescription(`please specify a role`)).then(x=>x.delete({timeout: 9000}))


  //In this part,I want to change the value in my config file. conf.perms.commands


    message.channel.send(`${rol} designated as the registration role.`)
        }
    
}};

module.exports = roller;
