Get the call transcript using the AWS connect streams java script library.

I will need a little bit more information about your use case to be able to answer accurately. In any case, connect-streams-js is not the right library for call transcripts. If you need the transcript in real time you need to use the Contact Lens streams API (https://docs.aws.amazon.com/connect/latest/adminguide/contact-analysis-segment-streams.html). For post call you can retrieve the transcript from the Contact Lens output file stored in the S3 bucket configured for your instance (https://docs.aws.amazon.com/connect/latest/adminguide/contact-lens-example-output-files.html).
