Question

I'm developing a TV Web application and need to implement push notifications. I've successfully registered with the Push Service and obtained a regID (starting with "05"), but despite sending notifications via Postman, my app isn't receiving them.

Key issues:

Push notifications aren't being received despite proper registration
The notification callback function isn't executing
Need to know if Firebase Cloud Messaging is a viable alternative
Need to display notifications when the app is in background

Additional details:

Using Korean API despite being in Europe
Included appID, appSecret, and Content-Type in headers
Tried modifying notificationCallback parameters without success
Explored Firebase Cloud Messaging but couldn't get ServiceWorker to work
