Add Author in say Command - discord

Question

I want to add in my command say the author of the message. Something Like That:
Hello World - #Author
I tried to do this alone but I failed I hope you can help me.)
I don't really understand why it wouldn't work, I tried to change a lot but it still gives me the message without the Author
My Current Code:
const Command = require('../structures/command.js');
const SubCommand = require('../structures/subcommand.js');
module.exports = class Say extends Command {
constructor(client) {
super(client);
this.name = "say";
this.subcommands = [new EmbedSay(client, this)];
}
run(message, args, commandLang, databases, lang) {
if (message.member.hasPermission('ADMINISTRATOR')) {
message.channel.send(args.join(' '));
message.delete();
} else {
var embed = this.client.getg1cuEmbed(message);
embed.setDescription(lang.missing_manageguild_permission);
embed.setColor(this.client.config.colors.error);
message.channel.send(embed);
}
}
}
class EmbedSay extends SubCommand {
constructor(client, parentCommand) {
super(client, parentCommand);
this.name = "embed";
this.aliases = ["--embed"];
}
run(message, args, commandLang, databases, lang) {
if (message.member.hasPermission('ADMINISTRATOR')) {
try {
var json = JSON.parse(args.join(' '));
} catch (e) {
var embed = this.client.getg1cuEmbed(message);
embed.setColor(this.client.config.colors.error);
embed.setTitle(commandLang.json_error_title);
embed.setDescription(commandLang.json_error_desc);
message.channel.send(embed);
return;
}
message.delete();
if (json.content) {
message.channel.send(json.content, json);
} else {
message.channel.send(json);
}
} else {
var embed = this.client.getg1cuEmbed(message);
embed.setDescription(lang.missing_manageguild_permission);
embed.setColor(this.client.config.colors.error);
message.channel.send(embed);
}
}
}

Answer 1

To gain the author of a message in discord.js simply:
To gain ID: message.author.id
To gain tag: message.author.tag
To gain a url: message.author or '<#!' + message.author.id + '>'

i am not really a fan of discord.js but i do know one thing, user.mention always works and it mentions the user who typed in the command. member.mention could also work as well.
If that doesn't work then I'm sorry for leading you off track, but maybe this will help: https://discord.js.org/#/docs/main/stable/general/welcome
