injectCredentialsAndInvokeV2 method in proxy class doesn't support API's like PutObject from S3.

I have a use case where I am uploading a file to S3 during create/update but based on the current proxy implementation, I don't see a method that does this for me because putObject has request, content and a response, I am currently using https://github.com/aws-cloudformation/aws-cloudformation-resource-providers-cloudformation/pull/6/files/1e7ca3fc2d9223b7ac244ca08258991b4216e2b8#diff-30f8eb54f5522067f6dd253e609e9ca24d587dc9610e2b2c745383ec55cba68f AwsCredentialsExtractor to extract the credentials and make a putObject request.

I would like to know if you may be have any suggestions/workarounds for this?

Start by inspecting the proxy class's injectCredentialsAndInvokeV2 method and the linked AwsCredentialsExtractor example. Compare the PutObject request, content, and response shape with the invocation paths currently supported. Done means the required S3-style API can be invoked through the proxy without manual credential extraction.
