Prefix s3 aws where to find

i am trying to upload 3d tiles from s3 bucket
have not succed to find where to copy from amazon to add data on cesion ion

If you got to the Add Assets page, you will see an Add from S3… button. That will display a form where you can provide your bucket, access credentials, and the prefix for the location of the files to import.

Please let us know if you have more questions about importing from AWS.
