How to give access to a command of a certain role?

Question

Node.js

Is it possible to give access to my team to only 1 or a couple of roles? For example, only Glav.Adminu.

function правила(robot, mess, args) {
  const exampleEmbed = new MessageEmbed()
  .setColor('#4C50BE')
  .setTitle('правила')
  .setDescription('правила')
  .setFooter({ text: '12.01.2022'});
  mess.author.send({ embeds: [exampleEmbed] });
}

I tried to search on the Internet, but I did not find a working option.

Answer 1

First, get the desired role:

let adminRole = mess.guild.roles.cache.get("ID_роли");
// или //
let adminRole = mess.guild.roles.cache.find(role => role.name === "название_роли");

after that, check if the author of the command has this role:

if (!mess.member.roles.cache.has(adminRole)) return "у пользователя отсутствует роль."
