I am using the AWS S3 v3 SDK and want to find out the size(in bytes or MB or GB ) of all the multipart uploads.

I tried using ListMultipartUploadsCommand but this does not give the size.

Below is the documentation I was referring to https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-s3/index.html

Which API do I have to use to get the relevant data?
