+ * Attempts to extract the underlying SdkException from an S3 encryption
client exception.
+ *
+ * <p>This method is designed to handle exceptions that may be wrapped within
+ * S3EncryptionClientExceptions. It performs the following steps:
+ * <ol>
+ * <li>Checks if the input exception is null.</li>
+ * <li>Verifies if the exception contains the S3EncryptionClientException
signature.</li>
+ * <li>Examines the cause chain to find the most relevant
SdkException.</li>
+ * </ol>
+ *
+ * <p>The method aims to unwrap nested exceptions to provide more meaningful
+ * error information, particularly in the context of S3 encryption
operations.
+ *
+ * @param exception The SdkException to analyze. This may be a wrapper
exception
+ * containing a more specific underlying cause.
+ * @return The extracted SdkException if found within the exception chain,
+ * or the original exception if no relevant nested exception is
found.
+ * Returns null if the input exception is null.
+ *
+ * @see SdkException
