AWS S3 auto save folder

Is there a way I can autosave autocad files or changes on the autocad files directly to S3 Bucket?, probably an API I can utilize for this workflow?
While I was not able to quickly find a plug in that does that for you, what you can do is one of the following:
Mount S3 bucket as a drive. You can read more at CloudBerry Drive - Mount S3 bucket as Windows drive
This might create some performance issues with AutoCad.
Sync saved files to S3
You can set a script to run every n minutes that automatically syncs your files to S3 using aws s3 sync. You can read more about AWS S3 Sync here. Your command might look something like
aws s3 sync /path/to/cad/files s3://bucket-with-cad/project/test

I have mounted s3 bucket on my EC2 instance using the details mentioned here at https://winscp.net/eng/docs/guide_amazon_s3_sftp. Also, I updated the bucket policy.
From winscp, I can see the list of files, add new files, delete files uploaded via s3 web portal, and open files uploaded by me via winscp.
However, I cannot open the file from winscp which I uploaded from s3 web portal. I get the following error.
Permission denied to read s3 object
