Thanks for asking question! Sorry, currently as the notice mentioned, When using Android Chat and Calling SDK together in the same application, Chat SDK's real-time notifications feature does not work.
The product group is aware of this and exploring supporting such a feature, but as of now not aware of publicly shareable date.
Thanks again for raising this issue.
Further would like to understand your scenario to help to you better on this.
If your requirement meet you can look for Event Grid.

Please note: Comparing to chat real-time notification, Event Grid does not support "TypingIndicator" and "ReadReceipt".
