Discord.js机器人有没有办法检查提及？

Question

Attached below is a part of my code. What it does is that if I type "pain.throw @user" it will throw out an embed and some text. However, if I don't mention a user, my code doesn't work. Is there a way someone can show me to let the bot spit out a message and say "You have to mention someone for this to work" or something. Thank you. Any help is appreciated.

const usernamegedUser = message.mentions.users.first();
