Section with youtube-nocookie video background

Hello,
I’m trying do usa a youtube-nocookie.com/embed video background for a section block, without success.
This snippet works for getwid/video-popup, core/embed but not for getwid/section, perhaps because of the use of Youtube api.

function csr_render_block( $block_content, $block ) {

if ( $block[‘blockName’] === ‘getwid/video-popup’ || $block[‘blockName’] === ‘getwid/section’ || $block[‘blockName’] === ‘core/embed’ ) {
// replace YT embed with https://www.youtube-nocookie.com/embed
$block_content = preg_replace(‘/youtube\.com\/embed/i’, ‘youtube-nocookie.com/embed’, $block_content);
$block_content = preg_replace(‘/youtube\.com\/watch/i’, ‘youtube-nocookie.com/embed’, $block_content);
}
return $block_content;
}
add_filter( ‘render_block’, ‘csr_render_block’, 99, 2 );

Any suggestion?
Thank you!
