Hello, I’m developing an using React Native and try to integrate the Sendbird Call into my app. I followed this tutorial [How to build a React Native video chat app with Sendbird Calls](https://sendbird.com/developer/tutorials/react-native-video-chat) but there’re some issue with Sendbird Call JavaScript SDK `undefined is not a function (near '...}).finally(function () {...')]` which make it cannot run on React-Native.

So I decide to implement in Native module by using Android and iOS SDK by forking and modifying one library I found and this is my fork [jason-supercoder/react-native-sendbird-calls](https://github.com/jason-supercoder/react-native-sendbird-calls). After implementing to my app and testing, the call never ringing on the callee side.

For example:  
User A calls User B → Not ringing  
User A calls User B + User B calls User A → now it rings on both sides.

Did I missed something why it doesn’t ring?

This issue has been solved by adding `FCM Server Key` to Sendbird call app notification settings
