TYPO3 - Load css file on init when extensions gets loaded in 8LTS? getPageRenderer() is depreciated

I used to load a css file when my extension gets loaded like this in 7LTS:

/**
 * Init
 *
 * @return void
 */
public function initializeAction() {

    $GLOBALS['TSFE']->getPageRenderer()->addCssFile('typo3conf/ext/myextension/Resources/Public/Css/myextension.css');

}

In 8LTS I get an error:

Uncaught TYPO3 Exception Call to undefined method TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController::getPageRenderer()

Supposedly getPageRenderer() is depcreciated:

https://docs.typo3.org/typo3cms/extensions/core/8.7/Changelog/8.0/Breaking-72424-RemovedDeprecatedTypoScriptFrontendControllerOptionsAndMethods.html?highlight=getpagerenderer

How can I load a css file when my extension gets loaded now?

I tried this but it's not working: 

/**
 * Init
 *
 * @return void
 */
public function initializeAction() {

    $pageRender = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Core\Page\PageRenderer::class);
    $pageRender->addCssFile('typo3conf/ext/myextension/Resources/Public/Css/basic.css');       

}

The duplicate link describes an alternative way (via templating) ... but not via an action ... so in my opinion no duplicate

The PageRenderer itself is not deprecated, just the method ->getPageRenderer() as the PageRenderer is now a Singleton.

So what you do is $pageRenderer = GeneralUtility::makeInstance(\TYPO3\CMS\Core\Page\PageRenderer::class); and you are fine.
