MusicKit is not defined

I'm trying to utilize MusicKitJS within my Vue project but keep running into the 'MusicKit is not defined' error. I added the cdn link into my HTML file as such:

Code Block <!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width,initial-scale=1.0" />
    <link rel="icon" href="<%= BASE_URL %>favicon.ico" />
    <title><%= htmlWebpackPlugin.options.title %></title>
  </head>
  <body>
    <noscript>
      <strong
        >We're sorry but <%= htmlWebpackPlugin.options.title %> doesn't work
        properly without JavaScript enabled. Please enable it to
        continue.</strong
      >
    </noscript>
    <div id="app"></div>
    <script src="https://js-cdn.music.apple.com/musickit/v1/musickit.js"></script>
  </body>
</html>

Code Block
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />

<link rel="icon" href="<%= BASE_URL %>favicon.ico" />

<title><%= htmlWebpackPlugin.options.title %></title>

<div id="app"></div>
<script src="https://js-cdn.music.apple.com/musickit/v1/musickit.js"></script>
</body>
</html>

Then I used this in a separate Javascript file called musicKit.js:

Code Block function setupMusicKit() {
  if (!MusicKit) {
    document.addEventListener("musickitloaded", () => {
      configure();
    });
  } else {
    configure();
  }
}
function configure() {
  MusicKit.configure({
    developerToken: process.env.VUE_APP_DEVELOPER_TOKEN,
    app: {
      name: "Vue Music",
      version: "1.0",
    },
  });
}
export default setupMusicKit;

Code Block
function setupMusicKit() {
if (!MusicKit) {
document.addEventListener("musickitloaded", () => {
configure();
});
} else {
configure();
}
}

function configure() {
MusicKit.configure({
developerToken: process.env.VUE_APP_DEVELOPER_TOKEN,
app: {
name: "Vue Music",
version: "1.0",
},
});
}

export default setupMusicKit;

I then immediately get this error:

~/musicKit.js
2:8 error 'MusicKit' is not defined no-undef
12:3 error 'MusicKit' is not defined no-undef

Maybe I read the docs wrong, but it mentions that MusicKit would be global after it was loaded. What am I doing wrong here? I've tried a variety of different ways of getting this to work all with the same error.

I've been able to use this setup with a basic HTML/Javascript project but I want to know how to set this up with Vue or even with React. I had the same problem in React as well so I don't know what I'm missing.
