The doc at https://vaadin.com/docs/latest/flow/routing/templates/#defining-route-templates-using-route-routealias-and-routeprefix mentions that there are documentation for the annotations `@Route`, `@RouteAlias `and `@RoutePrefix` at https://vaadin.com/docs/latest/flow/routing/layout. But the **Router Layouts and Nested Router Targets** documentation only includes docs for `@Route` and `@RoutePrefix`, and not `@RouteAlias` at all.
