``` TeamsExtension.MessageExtensions.OnQueryLink(async (ctx, state, url, ct) => { var preview = await _service.FetchPreviewAsync(url, ct); return new Response { ComposeExtension = new Result { Type = ResultType.List, Attachments = [preview.ToCard().ToMessagingExtensionAttachment()] } }; }); ``` Alternatively, the TeamsQueryLinkRouteAttribute can be used to decorate a QueryLinkHandler method for the same purpose.
