I have followed your suggestions and ensured that the Conversation Starter topic is enabled. I also re-added the agent in Teams after clearing the cache. However, after integrating the agent into the Teams channel, the starter message does not appear. The starter message topic only triggers when the user starts the conversation.
I have attached screenshots showing the agent's behavior in both Copilot Studio and the Teams channel.
Could you please help me check if I am missing any steps or if there is an issue with deploying the agent in the Teams channel?
