Chunking Base64 Files for REST Uploads in Retool with JavaScript

Hello,

I'm trying to send large data (e.g., a base64-encoded file) to a REST resource in Retool, but instead of sending it all at once, I'd like to stream it in chunks.

Is it possible to use something like a JavaScript generator or an async iterator in a Retool Query (or elsewhere in the app) to stream data chunk-by-chunk to a REST endpoint?
