Push Notifications Agent Example

Hi,

I’m currently exploring the A2A protocol and I’m looking for a Python example that demonstrates the following workflow:

- A client agent sends a task to another agent.
- The client agent continues executing other code after sending the task, without being blocked.
- The server agent processes the task and sends a push notification to the client once the task is completed.
- Ideally, the example would include a push notification webhook and clearly show the client’s non-blocking behavior.

I haven’t been able to find a sample covering this scenario. Could you point me to one, or provide guidance on implementing it using version 0.3.x?

Thank you in advance!
