Wrapping Gutenberg block

I want to use the Simple Sitemap Gutenberg block, but I need to wrap it in an extra div. How would I go about that?

I saw this example:

add_filter( 'render_block', 'wrap_table_block', 10, 2 );
function wrap_table_block( $block_content, $block ) {
  if ( 'core/table' === $block['blockName'] ) {
    $block_content = '<div class="example">' . $block_content . '</div>';
  }
  return $block_content;
}

Could I use something like that, if so what would I replace ‘core/table’ with?

Thanks
