• native_custom_fields_term_meta_fields
• native_custom_fields_user_meta_fields
• native_custom_fields_options_page_fields

add_filter( 'native_custom_fields_post_meta_fields', function( array $configs ): array {
    $post_type = 'book';

    if ( ! isset( $configs[ $post_type ] ) || ! is_array( $configs[ $post_type ] ) ) {
        $configs[ $post_type ] = [
            'post_type' => $post_type,
            'sections'  => [],
        ];
    }

    $configs[ $post_type ]['sections'][] = [
        'meta_box_id'       => 'post_options',
        'meta_box_title'    => 'Post Options',
        'meta_box_context'  => 'normal',
        'meta_box_priority' => 'default',
        'fields'            => [
            [
            'fieldType' => 'heading',
            'name' => 'post_heading',
            'fieldLabel' => 'Section Heading',

            'level' => 2,
