Asset Manager- Combining multipl css and js files

I have multiple css and js files that i registered in single app asset and registering in the view…class AppAsset extends AssetBundle
{
public $basePath = ‘@webroot’;
public $baseUrl = ‘@web’;
public $css = [
‘css/accessibility_css.css’,
‘css/aos.css’,
‘css/swiper-bundle.min.css’,
‘css/sweetalert2.min.css’,
‘css/style.css’,
‘css/leaflet.css’,
];
public $js = [
‘js/sweetalert2.all.min.js’,
‘js/main.js’,
‘js/pojo.min.js’,
‘js/aos.js’,
‘js/swiper-bundle.min.js’,
‘js/turn.min.js’,
‘js/pdf.worker.min.js’,
‘js/pdf.min.js’,
‘js/leaflet.js’,
];…and in view AppAsset::register($this);…but when i see the view source code of the view,i see multiple css and js file links…i want the assets to be combined into a single one so as to minimise network requests
