Fixed issue with error 403

Error:
403 GET /wp-json/wp/v2/types/dedo_download?context=edit&_locale=user HTTP/1.1

Solution:
/**
* Add REST API support to an already registered post type.
*/
add_filter( ‘register_post_type_args’, ‘my_post_type_args’, 10, 2 );

function my_post_type_args( $args, $post_type ) {

if ( ‘dedo_download’ === $post_type ) {
$args[‘show_in_rest’] = true;

}

return $args;
}
