Remarks

Decorate a method with this attribute to register it as a handler for message extension agent message preview send events in Teams. The method must match the MessagePreviewSendHandler delegate signature.

[TeamsMessagePreviewSendRoute("composeCmd")]
public async Task OnMessagePreviewSendAsync(ITeamsTurnContext turnContext, ITurnState turnState, IActivity activityPreview, CancellationToken cancellationToken)
{
    // Post the confirmed message to a channel or external system
    var content = activityPreview.Attachments?.FirstOrDefault()?.Content;
    await _channel.PostAsync(content, cancellationToken);
}

Alternatively, OnMessagePreviewSend(String, MessagePreviewSendHandler, String[], UInt16) can be used to register the handler via the fluent API.
