Query regarding ibm-cos-sdk computeChecksum implementation

I have used ibm-cos-sdk node package to upload files.

"ibm-cos-sdk": "^1.12.2"

This is how we are initializing ibm cos sdk. Here we do have option to enable computeChecksums.

import { S3 } from 'ibm-cos-sdk';

S3({ endpoint: '"', apiKeyId: '', serviceInstanceId: '', computeChecksums: true })

We are not sure where the computed check sum is stored and how we can access it.

Please provide the information on how to access calculated checksum for the uploaded object.

In the below example computeChecksums set it to false.

import { S3 } from 'ibm-cos-sdk';

S3({ endpoint: '"', apiKeyId: '', serviceInstanceId: '', computeChecksums: false });

To upload file using node js ibm-cos-sdk

cos.upload({ Bucket: BUCKET_NAME, Key: "TEST.PDF", Body: req, ContentMD5: md5Hash });

Could you provide me the steps how ContentMD5 will be validated in the ibm cos.

Thank you.
