Manage S3

Description

The Manage S3 module allows managing files in Amazon S3 buckets. It supports two operations: upload of PDF files from a URL and delete of existing files. In upload mode, it downloads the PDF from the URL provided in the input data and uploads it to the specified bucket. It is ideal for storing workflow-generated documents, backing up files, or managing cloud resources on AWS.
