Python: Bug: CopilotStudioAgent in Orchestration gets stuck, always timeout

[angandin]

Describe the bug
Using a CopilotStudioAgent in any orchestration pattern does not get any response, even after waiting tens of minutes. Using the same exact Agent with .get_response, it works perfectly.

To Reproduce

1. Use CopilotStudioAgent class (https://github.com/microsoft/semantic-kernel/blob/main/python/samples/getting_started_with_agents/copilot_studio/step1_copilot_studio_agent_simple.py) to define the CopilotStudioAgent
2. Use the ConcurrentOrchestration pattern (https://github.com/microsoft/semantic-kernel/blob/main/python/samples/getting_started_with_agents/multi_agent_orchestration/step1_concurrent.py), with just one agent defined in step 1
3. Execute code: value = await orchestration_result.get(timeout=20) will get stuck indefenitely

Expected behavior
Get result from orchestration_result.get() method, a text from the CopilotStudioAgent
