Just some notes on lerandash

Below are details on LearnDash Groups as requested:

LearnDash Groups ( slug: groups ) are a normal custom post type just like LearnDash Courses, or WooCommerce Products etc. Within the Group LearnDash has 3 associations:

1. Group Leaders - ( role slug: group_leader ) - When a Group Leader user is associated with a course there is a user_meta record created with the meta_key 'learndash_group_leaders_XXX' and the meta_value 'XXX' where 'XXX' is the Group Post ID.

2. Group Users - Similar to the above Group Leader for group users there is a user_meta record created with the meta_key 'learndash_group_users_XXX' and meta_value 'XXX' where 'XXX' is the Group Post ID. 

3. For Group Courses - ( slug: sfwd-courses ) - There is a post_meta record created to the Course Post ID with the meta_key 'learndash_group_enrolled_XXX' where 'XXX' is the Group Post ID. The meta_value will be a timestamp.

The majority of the LearnDash Groups management functionality is contained within the plugin code in includes/ld-groups.php there we have functions like:

learndash_group_has_course( $group_id, $course_id )
Used to check if a course is associated with a group

learndash_get_users_group_ids( $user_id = 0 )
For a User returns all Group Post IDs (array)

learndash_get_groups_users( $group_id )
For a Group ID return all associated User IDs.

We also have other functions like:
learndash_is_group_leader_user( $user_id )
Used to check if a specific User ID is a Group Leader.

Please let me know if you have any additional questions.

Thanks so much,
