Replacement for deprecated ObjectManager

TYPO3 Questions Fluid

Hi,
I have an ContentViewHelper to render single contents from table tt_content by uid.
Since TYPO3 10 ObjectManager is deprecated, I’m looking for a solution to replace $objectManager->get(…):

 /**
 * @param array $arguments
 * @param \Closure $renderChildrenClosure
 * @param RenderingContextInterface $renderingContext
 */
public static function renderStatic(
	array $arguments,
	\Closure $renderChildrenClosure,
	RenderingContextInterface $renderingContext
)
{
	$conf = [
		'tables' => 'tt_content',
		'source' => $arguments['uid'],
		'dontCheckPid' => 1
	];
	
	$objectManager = GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\Object\ObjectManager::class);
	return $objectManager->get('TYPO3\CMS\Frontend\ContentObject\RecordsContentObject')->render($conf);
}

This doesn’t work:

$cObject = GeneralUtility::makeInstance('TYPO3\CMS\Frontend\ContentObject\RecordsContentObject');
return $cObject->render($conf);

and leads to this exception:
Too few arguments to function TYPO3\CMS\Frontend\ContentObject\AbstractContentObject::__construct(), 0 passed in /html/typo3/typo3_src-10.4.32/typo3/sysext/core/Classes/Utility/GeneralUtility.php on line 3496 and exactly 1 expected

Can anyone help?
