Searchable posts index replicas not appearing in dashboard

[rob-wood-browser]

What did you expect to happen?

Custom replicas of the searachable_posts index to appear in the Algolia dashboard

What happened instead?

Replicas tab is still empty in the dashboard

How can we reproduce this behavior?

I've added the following to my functions.php file and pushed my settings via the plugin. Can't work out what i'm doing wrong!

add_filter( 'algolia_index_replicas', 'results_index_replicas', 10, 2);

function results_index_replicas( array $replicas, Algolia_Index $index ) {
    if ( 'searchable_posts' === $index->get_id() ) {
      $replicas[] = new Algolia_Index_Replica( 'post_date', 'asc' );
      $replicas[] = new Algolia_Index_Replica( 'post_date', 'desc' );
    }

    return $replicas;
}
