Need help in storing key along with value of _schemas topic using s3 sink connector.

[Pratik Shah]

Hi All,
          I am using kafka s3 sink connector ( version 4.0) to backup the
_schemas topic for its backup.
          The issue is that the content stored in S3 is only the value part
of the kafka message stored in _schemas topic.
          How can I configure the connector to store the key as well . I
have configured the key and value convertor to JSONConverter.
          But I am unable to get the expected output in the S3 object ?
Kindly provide your inputs.

Thank you in advance.
