Displaying a link to the avatar. Where is the error?

Question

JavaScript

Hello.
I'm trying to make a command for the bot to display the target's avatar.
I got a code that doesn't work.
Help me please.

spoiler

const { Command } = require('discord.js-commando');

module.exports = class avatarCommand extends Command {
  constructor(client) {
    super(client, {
      name: 'avatar',
      memberName: 'avatar',
      group: 'other',
      description: ""
    });
  }
  async run(message, args) {
    var avatar = author.avatarURL;
    message.reply("аватар:" + avatar);
  }
}

This is all code.
thanks in advance

And what exactly should work here?
Where does the author variable come from?
How will the bot get the token? Where is the main part of the work with the bot?
Don't use commando at all. What do you dislike about regular discrod.js?
