Series description

I’ve added a description for my series, and now I’m trying to call it in my theme. I tried these: term_description( 'series' ) term_description( string $taxonomy = 'series' ) term_description( $taxonomy = 'series' ) archive_description() series_description() I even tried: function term_description( $term = 0, $taxonomy = 'series' ) { if ( ! $term && ( is_tax() || is_tag() || is_category() ) ) { $term = get_queried_object(); if ( $term ) { $taxonomy = $term->taxonomy; $term = $term->term_id; } } $description = get_term_field( 'description', $term, $taxonomy ); return is_wp_error( $description ) ? '' : $description; } with no luck. Any suggestions? https://wordpress.org/plugins/series/
