Get a thread and page through its comments, oldest first, starting with the comment that opened it.
Comments are paginated: at most 250 are returned per request. Keep paginating for as long as a next_cursor is returned.
Supply created_after to return only the comments created after a timestamp, which is useful when polling a thread for new replies. The comment that opened the thread is returned only when it also satisfies the filter.
To view threads on records, you will need the object_configuration:read and record_permission:read scopes.
To view threads on list entries, you will need the list_configuration:read and list_entry:read scopes.
Required scopes: comment:read.
