Remarks

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

[TeamsMessagePreviewEditRoute("composeCmd")]
public Task<Response> OnMessagePreviewEditAsync(ITeamsTurnContext turnContext, ITurnState turnState, IActivity activityPreview, CancellationToken cancellationToken)
{
    // Re-open the compose form populated with the draft content
    var draft = activityPreview.Attachments?.FirstOrDefault()?.Content;
    return Task.FromResult(new Response { ComposeExtension = new Result { Type = ResultType.List, Attachments = [BuildEditCard(draft)] } });
}

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