Get ID on the Custom Post Type URL Slug

Hello, People .

I created a Custom Post Type Product. My current permalink is https://www.ads-software.com/sample-post/ , but I want my products to have URL like this: https://www.ads-software.com/%post_id%/sample-post/. but the slug is not pulling the ID. It simply goes with https://www.ads-software.com/product/sample-post/ slug.

//Product Post type
add_action( 'init', 'product_init' );

function product_init() {
    $args = array(
      'label' => 'Product',
        'public' => true,
        'show_ui' => true,
        'hierarchical' => false,
        'query_var' => true,
	'taxonomies' => array('category' ),
	'rewrite' => array('slug' => $post->ID ),
	'has_archive'   => true,
	'show_in_rest' => true,
	'capability_type'    => 'post',
        'supports' => array(
            'title',
            'editor',
            'thumbnail',
	    'custom-fields'
		  ));
	
    register_post_type( 'product', $args );
