fn is not defined (embed)

Bonjour,

Voila je rencontre un petit problème avec mon code.

Ce que je fais

voici mon code :

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

module.exports.run = (client, message, args) => {
let text = args.join(" ");
let channel = ("642010086721585192","642057422621507584");
if(!text) {return message.channel.send("Merci d'écrire un message qui sera envoyé à l'équipe support !")}
let embed= new Discord.RichEmbed()
.setColor("#000FF")
.setTitle("Question de"+ message.author.username)
.setDescription("Demamnde de support",(client.channels.filter(x => x.name === "support-bot").map(message.channel.send(text)))
.setFooter(message.author.username))
message.send({embed})}

module.exports.help = {
        name: 'support'
};

Ce que je veux

je souhaite qu'il envoie un embed dans un salon spécifique.

Ce que j'obtiens

voici mon (mes) erreurs :
comment les régler ? merci d'avance !
