How to connect styles and scripts to a WordPress plugin?

Question

WordPress

Good afternoon. I recently started making one plugin, and there was a problem that I can’t connect the styles and scripts that are in its directory to this plugin.
Tried something like this:

add_action('init', 'register_script');
function register_script() {
    wp_register_script( 'custom_jquery', plugins_url('/js/custom-jquery.js', __FILE__), array('jquery'), '2.5.1' );

    wp_register_style( 'new_style', plugins_url('/css/new-style.css', __FILE__), false, '1.0.0', 'all');
}

And many more like it. But there is no reaction. Suspicions fell on the fact that I may not be putting this code there. I put it in the main file name_plugin.php which lies at the root of the plugin.
Tell me how and where to insert it? Thank you.

    wp_register_script( 'custom_jquery', plugins_url('/js/custom-jquery.js', __FILE__), array('jquery'), '2.5.1' );
    wp_register_style( 'new_style', plugins_url('/css/new-style.css', __FILE__), false, '1.0.0', 'all');
    wp_enqueue_script('custom_jquery');
    wp_enqueue_style('new_style' );
}
