If your bucket list is empty, it may be because the `ListAllMyBuckets` permission is not granted. This permission allows the integration to retrieve and display all buckets in your account. You can still proceed by manually entering the bucket name in the input field. To grant the necessary permission, use the following IAM policy:

```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Action": ["s3:ListAllMyBuckets"],
      "Effect": "Allow",
      "Resource": ["arn:aws:s3:::*"]
    }
  ]
}
```

For more information on S3 IAM permissions, [refer to the documentation.](https://docs.aws.amazon.com/AmazonS3/latest/userguide/access-policy-language-overview.html)

Only fetch files within this folder (will also trigger off of new files in subfolders of this folder). Example: `folder/` or `folder/subfolder/`.

The url of the object to retrieve. It should be in the format `s3://bucket-name/key-name` or `https://bucket-name.s3.amazonaws.com/key-name`.

Specify the unique key for the object being uploaded. This key can include folder/subdirectory paths to help organize your files within the S3 bucket. Use a forward slash (`/`) to separate different levels of hierarchy. Examples: `file.txt` uploads the file to the root of the bucket. `folder1/file.txt` uploads the file to `folder1`. `folder1/subfolder1/file.txt` uploads the file to `subfolder1` within `folder1`.

Set this to true if you want to keep the leading slash on key names.

Must be a file object from another service (or some text). We recommend keeping files under 500mb or so - depending on the source download speed we can timeout if the file is too large.

Use `auto` for us to guess, `none` for no value (S3 default) or something like `plain/text` if you want to be explicit.
