Have a reverse route match multiple Request Methods in Play Framework

RequestMethods.scala

object MyController extends Controller with StrictLogging {
  
  def index =
    AdminAction.async { implicit request =>
      request.method match {

        case "GET" =>
          Future.successful(Ok("GET"))

        case "POST" =>

          def onError(errors: Form[FooCreateDirective]): Future[Result] = {
            Future.successful(BadRequest("ERROR"))
          }

          def onSuccess(directive: FooCreateDirective): Future[Result] = {
            operation(directive) map {
              case Success(_) => Redirect(routes.MyController.index())
              case Failure(e) =>
                logger.error("MyController.createOnSuccess failed", e)
                InternalServerError
            }
          }

          fooCreateForm.bindFromRequest().fold(onError, onSuccess)

        case _ => Future.successful(MethodNotAllowed(request.method))
      }
                      }
  }
}
