Push notifications send bird messaging

I am using sendbird library as a messaging client in react-native. I aim to receive push notifications triggered by sendbird in a channel. I did all the configuration from my side by following documentation given by send bird. Even token is also successfully registered by sendbird. But, when I send message in a group channel the other user of the same channel is not receiving it.

Using below line of code to trigger notifications.

Have used react-native-firebase for notifications as sendbird by default use Firebase for triggering notifications.

    groupChannel.setMyPushTriggerOption('default', function(response, error) { if (error) { return; }  // Do something in response to setting });
