I'm on v12 and after a lot of time I decided to start coding again but I ran into a problem I can't quite fix. At start I wanted to add a function to the Message class like so

Discord.Message.prototype.no = function(content){
  this.channel.send(`:x: - ${content}`)
};

But after a while I saw that some messages I sent did not have this function and threw me an error msg.no is not a function I used console.log to see what didn't have the function and it wasn't a Message, it was a ExtendedMessage class.

My question is, what's ExtendedMessage ? I found nothing about it on the documentation and when searching for it on google, I only found things related to inline replies etc.. Discord don't have a class ExtendedMessage

I tried deleting node_modules and reinstalling everything again but it didn't help.
