syncing to and from WorkDocs and S3

i am working on a solution to be able to utilize WorkDocs for its in-app ability to edit documents without the need to download them to a computer but i need to be able to access the CSVs that are edited on other services, like i can with S3. So I'm looking a way to get WorkDocs and 3s to sync both ways not just replicate one to the other. so if something is placed on WorkDocs it needs to show up in s3 and if we place something in S3 it needs to show up in WorkDocs. is there an up-to-date guide to accomplish this as the ones i found were written 2021 and some of the lambda stuff looks different making it hard to follow, as i don't fully understand the ends and out of lambda like I do many of the other services, so i can't just look at it and know it means this but it say that.
