I'm seeking guidance on accessing the request object from a JavaScript function in order to update the headers, and generate an AWS Signature V4.
To generate an AWS Signature V4, you need to access the existing headers (accept, content-type, host), and the actual request body as those are necessary to calculate the signature.
I have reviewed the configuration headers, but I am uncertain how to access the current request, or if only the body and headers are necessary.
