do_rename function does not exist

Hello,

I am very new to wordpress development and I am trying to use the plugin to create a REST endpoint that will allow my users to rename media. Here is what my route registration looks like:

add_action( 'rest_api_init', 'custom_routes');
function custom_routes(){
	register_rest_route('custom/media/v1', 'rename_media',array(
		'methods'  => array( 'POST' ),
		'callback' => 'media_rename',
		'args' => array('media_id' => 'string',
						'new_name' => 'string')
	));
}

function media_rename($request) {
    $params = wp_parse_args( $request->get_params(), [
    	'media_id' => '-1',
    	'new_name' => ''
  	] );

    $args = array(
        'media_id' => $params['media_id'],
		'new_name' => $params['new_name']
    );
	
	$result = -1;
	if (function_exists('do_rename'))
	{
	    $result = do_rename($args['media_id'], $args['new_name']);
	}
    
    if ($result != 1) {
    	return new WP_Error( 'empty_category', 'no image found', 		array('status' => 404) );
    }

    $response = new WP_REST_Response($params['new_name']);
    $response->set_status(200);

    return $response;
}

`

However, when I call function_exists('do_rename') from my media_rename function it returns false. If I don’t do the check and try to call do_rename then I get an internal server error. Any insight as to what I am doing wrong or how I can fix this?
