Sending web push notifications in web apps and browsers Enable push notifications for your webpage or web app. Prepare your server to send push notifications.

User Denied Permission: The user has denied permission to use service workers. This could be due to the user's browser settings, or their device not supporting service workers. You may need to ask the user to allow service workers in their browser settings, or use a different browser that supports service workers.
In addition to caching, Service Workers can also handle push notifications, synchronize data in the background, and provide an offline fallback experience.
