Adding css resource available to all component in the application using wicket 9.x

[Arunachalam Sibisakkaravarthi]

Hi guys,
I am doing Wicket migration from 7.x to 9.x
In Wicket7.x I add css resource as below, it was working

getHeaderResponseDecorators().add(getHeaderResponseDecorator());

private IHeaderResponseDecorator getHeaderResponseDecorator()
{
    return response -> {
        response.render(CssHeaderItem.forReference(css1));

        response.render(CssHeaderItem.forReference(css2));

return new JavaScriptFilteredIntoFooterHeaderResponse(response, "scripts");
};

whereas the above one doesn't work in Wicket9.x
Is there any alternative to css and js in init() method of WebApplication?
so that css/js will be available to all components.
