Advanced Layout Builder

Anyone who wants to activate the “Advanced Layout Builder” in the event description can use this code: (It works for me with Enfold-Theme)

// EventPrime ALB Metabox
add_filter('avf_builder_boxes', function($metaboxes) {
    $metaboxes[] = array(
        'title' => 'Avia Layout Builder',
        'id' => 'avia_builder',
        'page' => array('em_event', 'em_performer'),
        'context' => 'normal',
        'priority' => 'high',
        'expandable' => true
    );
    return $metaboxes;
});
