I am trying to print get embed message in discord, but this happens:

TypeError: Discord.RichEmbed is not a constructor

Here is my code:

const Discord = require('discord.js');

const bot = new Discord.Client();

const token = 'mytokenhere';

const prefix = '!';



bot.on('ready', () => {

    console.log('This bot is online!');

});



bot.on('message', message => {

    let args = message.content.substring(prefix.length).split( );



    switch(args[0]) {

        case 'pomoc':

            message.channel.send('.')

            break;

        case 'cc':

            if(!args[1]) return message.reply('Podaj 2 argument! (liczbe wiadomosci do skasowania)')

            message.channel.bulkDelete(args[1]); 

            break;

        case 'embed':

            var embed = new Discord.RichEmbed()

                .setAuthor(message.author.username)

                .setDescription(Usuario rikolino.)

                .setColor(#3535353)

                .addField(Usuario, '${message.author.username}#${message.author.discriminator}')

                .addField(ID, message.author.id)

                .addField(Creación, message.author.createdAt);



            message.channel.send({embed});

            break;

    }

});



bot.login(token);

I tried many other solutions, but the result is always the same, I really don't know where the problem is.
