Hello,
please add Rankmath support for the table of content element. Right now it doesn’t recognize that it is there and can not help to optimize titles and structure. More:
/**
* Filter to add plugins to the TOC list.
*
* @param array TOC plugins.
*/
add_filter( 'rank_math/researches/toc_plugins', function( $toc_plugins ) {
$toc_plugins['plugin-directory/plugin-filename.php'] = 'Plugin Name';
return $toc_plugins;
});
