Azure Functions - NodeJS - Response Body as a Stream

I'd like to return a file from Blob Storage when you hit a given Azure Function end-point. This file is binary data.

Per the Azure Storage Blob docs, the most relevant call appears to be the following since its the only one that doesn't require writing the file to an interim file: getBlobToStream

However this call gets the Blob and writes it to a stream.

Is there a way with Azure Functions to use a Stream as the value of res.body so that I can get the Blob Contents from storage and immediately write it to the file?
