Custom post type

To enable block editing on custom post type :

function create_post_type (){
    $args = array(
        ...
        'support'			=> array('title', 'thumbnail'),
        'show_in_rest'		=> true,
        ...
    );
    register_post_type('new-cpt-slug', $args);
}
add_action('init', 'create_post_type', 9);

Custom taxonomies :

$args = array(
		...
		'rewrite'				=> array('slug' => 'profil'),
		'show_in_rest'			=> true,
	);
register_taxonomy( 'custom_tax_slug', ['cpt_slug'], [$args] );
