Notification feature like facebook

what is the approach of implementing a notification on emberjs? The notification what I was talking about is notification like facebook. For example, a pop-up notification will show when a person commented on your post or etc. I was thinking of using FCM (Firebase Cloud Messaging) or can someone share their experience (code) or knowledge if you have implemented this without using FCM. Would appreciate any suggestions, thank you!
