Ask HN: Any service/ways to get slack (weekly) digest per workspace?

Hi HN!

I would like to sync the best part of slack discussions as archives that could be searched by google(like what we used to do with IRC), is there any best practices on this? I noticed the Slack API provided event related to messages, in theory, could be leveraged, while I wonder if there is anything on digest level that already could be used.

Thanks! BR//Wey
