typescript support for Beam in Kinesis Analytics

Hi, I'm trying to figure out if Typescript is supported in Kinesis Data Analytics using Beam. I found this tutorial that uses Java, Flink, & Beam: https://docs.aws.amazon.com/kinesisanalytics/latest/java/examples-beam.html

Apache Beam source code has some examples of running Typescript with Flink https://github.com/apache/beam-starter-typescript , so I was wondering if the same runtime will support Typescript.

Would this work: zip up the whole typescript source code, put it in S3, & point the Code Location at that zip file?

Is Typescript + Flink support (and tutorial) on the roadmap for Kinesis Data Analytics?

Thanks for any pointers.
