    The parameter `boto3_options` allows you to pass the following information:
 
    - `region_name`: Your AWS region name.
-   - `endpoint_url`: specifies an S3 endpoint. Set this to connect to an S3-compatible object store (Amazon S3, or a compatible provider such as Backblaze B2, Cloudflare R2, or MinIO); leave it unset for Amazon S3.  You can provide an environment variable reference such as `"${S3_ENDPOINT}"` to securely include this in your code.  The string `"${S3_ENDPOINT}"` will be replaced with the value of the environment variable `S3_ENDPOINT`.
