    // examble configuration for linode
    RegionEndpoint = Amazon.RegionEndpoint.EUCentral1,
    ServiceURL = "https://eu-central-1.linodeobjects.com",
};

using (var client = new AmazonS3Client(AccessKey, SecretKey, config))
{
    var listResponse = await client.ListObjectsAsync(BucketName);
    
    var deleteResonse = await client.DeleteObjectsAsync(new()
    {
        BucketName = BucketName,
        Objects = listResponse.S3Objects
                  .Select(s3Object => new KeyVersion() { Key = s3Object.Key })
                  .ToList(),
