Access yop poll data with rest api?

What is the best way to access poll data using custom hooks with wp rest api?

I can access poll options, but cannot find the function to get results. Any suggestions would be helpful.

Here is my sample code:

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

add_action( 'rest_api_init', 'register_api_hooks' );
function register_api_hooks() {

	register_api_field(
		'post',
		'Yop-poll',
		array(
			'get_callback'    => 'get_poll_data',
		)
	);

}
// Return poll data
function get_poll_data( ) {

	return get_yop_poll_meta(1, 'options', true );

}
