Chrome extension with Firebase Cloud Messaging API: Defualt notification on msedge

Question

I have programmed an Chrome Extension with Manifest Version 3, and it works very well in chrome with no problems. I use Firebase Cloud Messaging API V1 to get messages from my server to clients. However the problem is that when i use the extensions in MS Edge it pops up with the default notification as well as my custom one in the push event.

So my question is how do i get it to work in edge without it sending the "This site has been updated in the background" and my custom one at the same time. Rather i want only my custom notification to be shown.

I have tried doing research online as to how i can resolve the issue, however that does not seem to be much information on the web directly related to ms edge and only chrome instead.

manifest.json:

{
    "name": "Staines Memorial College Notifications",
    "version": "1.0.1",
    "description": "Recieve notifications for Staines Memorial College and the Diary App.",
    "manifest_version": 3,
    "author": "Braydan Mengel - Staines Memorial College",
    "action": {
        "default_popup": "Ext_Status.html",
        "default_title": "Staines Memorial College Notifications Extension"
    },
    "permissions": [
        "notifications",
        "background",
        "storage"
    ],
    "background": {

        "type": "module"

//Login message handler
chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
    if (message.type === 'login') {

        const response = { status: 'success' };
        sendResponse(response);

        RegTopic();
    }
});

// Notification handlers
self.addEventListener('notificationclick', function (event) {
    const clickedNotification = event.notification;
    const linkOpening = clickedNotification.data.linkOpening;

    if (linkOpening !== 'NONE') {
        event.waitUntil(
            clients.openWindow(linkOpening)
        );
    }
});

self.addEventListener('notificationclose', function (event) {
    const clickedNotification = event.notification;
    const linkOpening = clickedNotification.data.linkOpening;

    if (linkOpening !== 'NONE') {
        event.waitUntil(
            clients.openWindow(linkOpening)
        );
    }
});

Note that i use version 9.0.0 of firebase-app.js, firebase-messaging.js, and firebase-messaging-sw.js. These files are packaged with the extension.

Here is the directory tree if you need it:
