might fail if containers > 5000 as incomplete_vector will not be the full list of containers

                // there should be a method in the list builder that we can pass token back to
                .next_token(_token)
                .execute().await;
   let container_vec = containers.unwrap().incomplete_vector;
    _found = container_vec.iter().any(|item| item.name == bucket_name);
   if _found || container_vec.is_complete() {

   } else {
    // obtain the token for the next batch of 5000
    _token = container_vec.token().expect("").clone().to_owned();
