Microsoft 365 Copilot agents dynamically reflect updates such as new suggested prompts. When an agent is updated, users who already have the agent installed do not need to reinstall or have the agent reshared. Instead, the updated configuration becomes available when the agent is used again.

Suggested prompts are surfaced when a user interacts with the agent. Therefore, once Ben Smith issues any prompt to Agent1, the agent session refreshes and displays the latest suggested prompts, including the newly added one.

Stopping and resharing the agent (Option A) or reinstalling it (Option B) is unnecessary overhead. Option D refers to a non-standard command and is not part of Microsoft Copilot functionality.

Thus, the correct action is simply to have the user interact with the agent again.
