Error with core patterns

• I created a custom post type and added support for patterns.
• I created and added a restaurant-single.php inc/patterns folder.
• I also added restaurant-single file to patterns folder.
• I then created this code:

// Register Custom Post Type
function register_restaurant_post_type()
{
	$args = array(
		'public' => true,
		'label'  => 'Restaurant',
		'menu_icon' => 'dashicons-food',
		'show_in_rest' => true,
		'supports'    => array('featured-image', 'thumbnail', 'custom-fields', 'excerpt', 'title', 'editor'),
		'template' => array(
			array('core/patterns', array(
				'slug' => 'twentytwentytwo/restaurant-single',
			)),
		),
	);
	register_post_type('restaurant', $args);
}
add_action('init', 'register_restaurant_post_type');

But unfortunately I was getting the following error message while to created a post in Restaurant:

Your site doesn’t include support for the “core/patterns” block. You can leave this block intact or remove it entirely.

I am not sure what is missing. If I comment out

'template' => array(
			array('core/patterns', array(
				'slug' => 'twentytwentytwo/restaurant-single',
			)),
		),

the error goes away but then it will defeats the purpose of creating a reusable pattern.

I am not sure why it’s saying the “site doesn’t include support for the core/patterns block.” I will appreciate some help.
