Show UI notification for incoming call


I’m developing an Ionic 4 app that uses Tokbox video-chat. How can I make a phone call notification? Any ideas?

I use firebase cloud messaging for other notifications.

Thanks in advance!

Have you checked this?

This really you need to develop a UI for yourself. I worked on this earlier with tokbox, But We have designed our own UI after fcm triggers a call notification your designed UI should call (could be a modal?) and this includes Accept and reject buttons with there respective functionalities.
