discord.js .msg.channel.send().then promise not working

Question

So this is my code for sending an embed, that says Loading shop with the dots changing. However, I am getting a pretty strange error message, which first tells me the error is at msg.delete() with "UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'delete' of undefined" and then a second one at the second msg.edit() saying "Cannot read property 'edit' of undefined". I searched up the docs and many forums, but the .then() syntax should be right. Any idea?

var embed = new Discord.MessageEmbed().setColor("GOLD").setTitle("Loading shop");
    msg.channel.send(embed)
        .then(msg => {setTimeout(()=>{msg.edit(embed.setTitle("Loading shop."))}, 500)})
        .then(msg => {setTimeout(()=>{msg.edit(embed.setTitle("Loading shop.."))}, 500)})
        .then(msg => {setTimeout(()=>{msg.edit(embed.setTitle("Loading shop..."))}, 500)})
        .then(msg => {setTimeout(()=>{msg.edit(embed.setTitle("Loading shop"))}, 500)})
        .then(msg => {setTimeout(()=>{msg.edit(embed.setTitle("Loading shop."))}, 500)})
        .then(msg => {setTimeout(()=>{msg.edit(embed.setTitle("Loading shop.."))}, 500)})
        .then(msg => {setTimeout(()=>{msg.edit(embed.setTitle("Loading shop..."))}, 500)})
        .then(msg => {msg.delete()});

Answer 1

1. Do not use this all "thens"
2. Use await

const embed = new Discord.MessageEmbed().setColor("GOLD").setTitle("Loading shop");
  const msg = message.channel.send(embed); // i change to message because msg will be used as var name
        setTimeout(() => {
      // do stuff
      msg.edit(embed.setTitle("Loading shop.")); // etc..
}, 500);
