• I’m trying to highlight powershell and have added:

    function my_custom_languages( $languages ) {
    $languages[] = array(‘slug’ => ‘powershell, ‘mode’ => ‘PowerShell’, ‘label’ => ‘Powershell’) ;

    return $languages;
    }
    add_filter( ‘advanced_gutenberg_blocks_code_languages’, ‘my_custom_languages’ );

    While the block is displayed as it should, there is no markup for the code.

    What can be done?
