Replacing content with the_content filter hook

[titamrtn]

Problem Description

We actually use the hook filter "the_content" to change link to span if it contains /go/ word

add_filter( 'the_content', 'link_change', PHP_INT_MAX, 1 );
function link_change( $content ) {
	
	$content = preg_replace_callback( '/<a[^>]*href="([^"]*\/go\/[^"]*)"[^>]*>(.*?)<\/a>/i', function ( $matches ) {
		$classes = [];
		if ( preg_match_all( '/class="([^"]*)"/i', $matches[0], $classMatches ) ) {
			$classes = explode( ' ', $classMatches[1][0] );
		}

		$classes[] = 'qcd';

		$href = $matches[1];
		$text = $matches[2];

		return '<span class="' . implode( ' ', $classes ) . '">' . $text . '</span>';
	}, $content );

	return $content;
}

It works fine on page and posts.

Now we have a custom "page" or whatever it is created for a specific category using the Divi Theme Builder, and the filter "the_content" seems to not be applied on it.

The question: is the content created in Theme Builder applying the filter 'the_content'? if not how can we have the same behavior ?
