	if( ! current_user_can('group_leader') && ! current_user_can('administrator') ) {
		return;
	}

	wp_add_inline_script( 'learndash-front',
		'if( jQuery("#ld-expand-'.esc_html( $lesson_id ).'").length != 0 ) {
			jQuery("#ld-expand-'.esc_html( $lesson_id ).'").find(".ld-item-name").attr("title", '.esc_attr( $lesson_id ).')
		}'

add_action( 'learndash-topic-row-title-before', 'custom_add_title_to_course_topic_table', 10, 3);
function custom_add_title_to_course_topic_table( $topic_id, $course_id, $user_id ) {
	if( ! current_user_can('group_leader') && ! current_user_can('administrator') ) {
		return;
	}

	wp_add_inline_script( 'learndash-front',
		'if( jQuery("#ld-table-list-item-'.esc_html( $topic_id ).'").length != 0 ) {
			jQuery("#ld-table-list-item-'.esc_html( $topic_id ).'").find(".ld-topic-row").attr("title", '.esc_attr( $topic_id ).')

Place this snippet in your theme's functions.php file and a link title with the topic/lesson ID will be added inside the LeanrDash course content table with each lesson and topic
