Microsoft Copilot Studio itself doesn’t natively poll a Teams channel on a timer (e.g., every 5 minutes). For that, you typically use Microsoft Power Automate with a scheduled trigger or Teams trigger, then pass the message into Copilot (or an agent flow).
Sending replies with Adaptive Cards:
Yes, you can send a response back to a Teams channel using Adaptive Cards. This is commonly done via Power Automate or a bot action after generating the AI response.
Do you need Agent Flow?
If your logic is simple (fetch → generate → respond), Power Automate is enough.
Use an Agent Flow (Copilot Studio orchestration) if you need more complex multi-step reasoning or tool use.
Triggering Agent Flow from Adaptive Card:
Not directly. Adaptive Cards don’t trigger flows by themselves — you need an action (e.g., submit) that calls Power Automate or a bot endpoint, which then invokes the Agent Flow.
