Get Framework and template params in Joomla 4

Question

Joomla 4 is coming soon and i need to know how to get the joomla framework and template params in php files outside of joomla.

This is the way in J3:

define( '_JEXEC', 1 ); 
define( '_VALID_MOS', 1 ); 
define( 'JPATH_BASE', realpath(dirname(__FILE__).'/../../..' ));
define( 'DS', DIRECTORY_SEPARATOR ); 
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' ); 
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' ); 
$mainframe = JFactory::getApplication('site'); 
$mainframe->initialise(); 

$app = JFactory::getApplication();
$template   = $app->getTemplate(true);
$params     = $template->params;

Thanks Marco

define('_JEXEC', 1);
define('JPATH_BASE', __DIR__ . '/../../..');
require JPATH_BASE . '/includes/defines.php';
require JPATH_BASE . '/includes/framework.php';

// Boot the DI container.
$container = \Joomla\CMS\Factory::getContainer();

// Alias the session service key to the web session service.
$container->alias(\Joomla\Session\SessionInterface::class, 'session.web.site');

// Get the application.
$app      = $container->get(\Joomla\CMS\Application\SiteApplication::class);
$template = $app->getTemplate(true);
$params   = $template->params;
