Require.js - "Module name... has not been loaded yet for context:"

Question

So I'm very new to require.js and I'm confused as fug. Can someone tell me why I'm getting the message "Module name "kahoot.js" has not been loaded yet for context" when I require it at the top of the script?

    <script>
        require(['config'],function() {
            require(['script']);
            var Kahoot = require("kahoot.js");
            var client = new Kahoot;
            console.log("Joining kahoot...");
            client.join(gamePin,"kahoot.js");
            client.on("joined", () => {
                console.log("I joined the Kahoot!");
            });
            client.on("quizStart", quiz => {
                console.log("The quiz has started! The quiz's name is:", quiz.name);
            });
            client.on("questionStart", question => {
                console.log("A new question has started, answering the first answer.");
                question.answer(0);
            });
            client.on("quizEnd", () => {
                console.log("The quiz has ended.");
            });
        });
    </script>
