Accessing HAR files for most recent crawl

From other posts it is my understanding is that only the HAR files from the most recent crawl are retained. I was wondering if there are instructions as the how to access that data directly rather than reconstructing it from the data in BigQuery, if that is still possible?

Links to HAR files in older posts seem to no longer work. For example, the links in https://discuss.httparchive.org/t/downloading-har-datasets-later-than-may-2022/2588 give me permission errors.
