Making only admins execute commands - discord

Question

The problem is that I couldn't figure out a way to make this command only accessible by admins. I've tried using if statements, however, I failed. message. I am not sure if member. roles. cache. has( ' 732524984777572363 ' ) would allow members with the role ID 732524984777572363 to execute it since there's already an if statement.
const Discord = require('discord.js');
const fs = require('fs');
const cooldown = new Set();
module.exports.run = async (client, msg, args, config) => {
if(cooldown.has(msg.author.id)) {
msg.reply(`You need to wait ${config.COOLDOWN} minutes to use this command again!`)
.then((m) => {
msg.delete();
setTimeout(() => {
m.delete();
}, 5000);
});
} else {
fs.readFile('./accounts/crunchy.txt', 'utf8', function(err, data) {
if (err) throw err;
data = data + '';
var lines = data.split('\n');
let account = lines[Math.floor(Math.random() * 1)];
fs.writeFile('./accounts/crunchy.txt', lines.slice(1).join('\n'), function(err) {
if(err) throw err;
});
let embed = new Discord.RichEmbed()
.addField('Rate Us Here | قيمنا هنا ', `<#915***********80>`)
.addField('CrunchyRoll Account',`\n**${account}**`)
.setThumbnail('**************************')
.setColor("#363940")
.setFooter('Bot made by ******')
.setTimestamp();
msg.author.send(embed);
msg.reply('I\'ve sent you the account! Please check your DM!')
.then(m => {
setTimeout(() => {
m.delete();
}, 900000);
});
cooldown.add(msg.author.id);
setTimeout(() => {
cooldown.delete(msg.author.id);
}, config.COOLDOWN * 60 * 1000);
});
}
};
module.exports.help = {
name: `CrunchyRoll`,
description: `Sends you a CrunchyRoll account!`
};```

Simply adding a role check and a server check will prevent any issues!
The first line would be:
if(!msg.guild) return;
This line makes sure the user is running the command in a server(guild), this prevents a member role from being undefined or null.
The second line would be:
if(!msg.author.roles.cache.has('ROLE_ID_HERE')) return;
This prevents a user from running a command if they do not have a specific role.
The final code would be:
if(!msg.guild) return;
if(!msg.author.roles.cache.has('ROLE_ID_HERE')) return;
You will need to add this to the top of your code in order for it to work as you'd like.
const Discord = require('discord.js');
const fs = require('fs');
const cooldown = new Set();
module.exports.run = async (client, msg, args, config) => {
if(!msg.guild) return;
if(!msg.member.roles.cache.has('ROLE_ID_HERE')) return;
if(cooldown.has(msg.author.id)) {
msg.reply(`You need to wait ${config.COOLDOWN} minutes to use this command again!`)
.then((m) => {
msg.delete();
setTimeout(() => {
m.delete();
}, 5000);
});
} else {
fs.readFile('./accounts/crunchy.txt', 'utf8', function(err, data) {
if (err) throw err;
data = data + '';
var lines = data.split('\n');
let account = lines[Math.floor(Math.random() * 1)];
fs.writeFile('./accounts/crunchy.txt', lines.slice(1).join('\n'), function(err) {
if(err) throw err;
});
let embed = new Discord.RichEmbed()
.addField('Rate Us Here | قيمنا هنا ', `<#915***********80>`)
.addField('CrunchyRoll Account',`\n**${account}**`)
.setThumbnail('**************************')
.setColor("#363940")
.setFooter('Bot made by ******')
.setTimestamp();
msg.author.send(embed);
msg.reply('I\'ve sent you the account! Please check your DM!')
.then(m => {
setTimeout(() => {
m.delete();
}, 900000);
});
cooldown.add(msg.author.id);
setTimeout(() => {
cooldown.delete(msg.author.id);
}, config.COOLDOWN * 60 * 1000);
});
}
};
module.exports.help = {
name: `CrunchyRoll`,
description: `Sends you a CrunchyRoll account!`
};
