Describe the bug

When leveraging the botbuilder-python package and connected to Teams, no messages are shown in Teams. Messages from Teams get delivered in the botbuilder implementation, but no messages are broadcasted from the bot.

Related issue: #2210. When I fix this issue by commenting out this code, I end up with the next issue.

To Reproduce

Steps to reproduce the behavior:

1. Create a Bot Service bot with botbuilder-python
2. Declare a Custom Engine agent (https://learn.microsoft.com/en-us/microsoft-365-copilot/extensibility/overview-custom-engine-agent) in the manifest
3. Test your bot in Teams

Expected behavior

Activities ending up in my M365 Custom Engine Agent.
