The message extension command ID to match. Mutually exclusive with commandIdPattern.
- commandIdPattern
- String
The message extension command ID pattern to match using regular expressions. Mutually exclusive with commandId.

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.
