Wordpress - adding Featured image to custom Post T

Question

I'm trying to add a Featured Image to my theme but not for Posts or Pages - I've created a custom type called Properties (its for an estate agent), so how do I enable Featured Image, as it doesn't appear in the sceen options?

Hope someone can help,

$property  = new Cuztom_Post_Type( 'Property', array(
    'supports' => array('title', 'editor')
));

Answer 1

100% working this code

 add_theme_support('post-thumbnails');
add_post_type_support( 'news', 'thumbnail' ); 

function create_posttype() {
    register_post_type( 'news',
        array(
            'labels' => array(
                'name' => __( 'News' ),
                'singular_name' => __( 'news' )
            ),
            'public' => true,
            'has_archive' => true,
            'rewrite' => array('slug' => 'news'),
            'menu_icon' => 'dashicons-format-aside',

        )
    );
}
add_action( 'init', 'create_posttype' );

Answer 2

$property  = new Cuztom_Post_Type( 'Property', array(
    'supports' => array('title', 'editor', 'thumbnail')
));

I appear to have solved my own question - see above

    add_theme_support('post-thumbnails');
    add_post_type_support( 'testimonial', 'thumbnail' );

                    'singular_name' => __( 'testimonial' )

                'has_archive' => true,
                'rewrite' => array('slug' => 'testimonial'),
                // add category in custom post type
                'taxonomies' => array( 'category'),
            )
        );
    }
