Firebase messaging from bubble

I've got a simple HTML element in Bubble.io that I'm trying to run javascript from.

Here's the error:

Uncaught Error: Service messaging is not available
    at Provider.getImmediate (provider.ts:130:15)
    at getMessagingInWindow (api.ts:64:61)
    at about:blank:35:19

and here's the pseudocode:

<script type="importmap">
{
    "imports": {
        "firebase/app": "https://www.gstatic.com/firebasejs/9.6.6/firebase-app.js",
        "firebase/messaging": "https://www.gstatic.com/firebasejs/9.6.9/firebase-messaging.js"
    }
}
</script>
  <script type="module">
   import { initializeApp } from 'firebase/app';
   import { getMessaging } from 'firebase/messaging';
   const firebaseConfig = {
   //...my config
   };

   // Initialize Firebase
   const app = initializeApp(firebaseConfig);
   const messaging = getMessaging(app); // ERROR HERE
   console.log(messaging)
</script>

Has anyone solved this? How can I run the push notifications script from a bubble page?

The versions of your Firebase SDK imports are mismatched. Make sure they are always the same version. It's also a good idea to make sure you're on the latest.
