Notification is not showing up - google-chrome-extension

Question

I read this and trying to make simple extension that is displaying notification, so I wrote the below:
// background.js
let color = '#3aa757';
chrome.runtime.onInstalled.addListener(() => {
chrome.storage.sync.set({ color });
});
chrome.contextMenus.create({
"id": "sampleContextMenu",
"title": "Sample Context Menu",
"contexts": ["selection"],
});
// Example of a simple user data object
const user = {
username: 'demo-user'
};
chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
// 2. A page requested user data, respond with a copy of `user`
if (message === 'get-user-data') {
showStayHydratedNotification()
sendResponse(user);
}
});
function showStayHydratedNotification() {
chrome.notifications.create('NOTFICATION_ID', {
type: 'basic',
iconUrl: '../m.png',
title: 'notification title',
message: 'notification message',
priority: 2,
buttons: [
{
title: 'Yes'
},
{
title: 'No'
}
]
})
}
And
//content-script
document.body.style.backgroundColor = 'orange';
console.log('Hello')
// 1. Send the background a message requesting the user's data
chrome.runtime.sendMessage('get-user-data', (response) => {
// 3. Got an asynchronous response with the data from the background
console.log('received user data', response);
// initializeUI(response);
});
My manifest is:
{
"name": "Getting Started Example",
"description": "Build an Extension!",
"version": "1.0",
"manifest_version": 3,
"background": {
"service_worker": "js/background.js"
},
"permissions": ["storage", "activeTab", "contextMenus", "scripting", "alarms", "notifications"],
"options_page": "html/options.html",
"action": {
"default_popup": "html/popup.html"
},
"content_scripts": [
{
"matches": ["http://*/*", "https://*/*"],
"exclude_matches": ["*://*/*business*"],
"run_at": "document_idle",
"css": ["css/my-styles.css"],
"js": ["js/content-script.js"]
}
]
}
The extension structure is:
When I load the page, everything in the extension is working fine, except the notification, it is not showing up, and I'm not getting any error:
What could be the mistake I made?
