Im getting CSS and JS not found laravel 9 app

I’m trying to add a custom UI to my Laravel 9 app. So I’m adding extra CSS and JS files to my app.blade.php But looks like its not loading properly.

enter image description here

As you can see http://127.0.0.1:8000/css/tailwind.output.css and http://127.0.0.1:8000/js/init-alpine.js files not loaded. But when i check default http://127.0.0.1:8000/css/app.css file. Its working. But both of these files resides in the same location, which is resources/css/ and resources/js/ folders. Why those custom css and js files not loaded.
