Is there a solution to get notified using #Twilio #Flutter?

When we are not in the chat page, we need to get notified to understand a message has received.
We use this library: twilio_chat_conversation: ^1.0.4
which is here: https://pub.dev/packages/twilio_chat_conversation
We have prepared whole chat functionality except #notifications but notifications are not working. Is there any solution to get notified? If there is, please contact with me? (If you think it is possible via channel method, please could you explain it)
