Does anyone know how to export data from the React Health app? (Luna G3, iOS)

I have a Luna G3 machine that outputs very basic metrics over a datalink connection. (Nothing that could be used for OSCAR; just hours, AHI, and leak.) It shows up for my doctor and in the React Health app.

Does anyone know how I can export the data from the app? I really wish the app connected to Apple Health, but it doesn’t. Specifically, I want to get it into the Guava app, but I would also settle for anywhere else like a spreadsheet.

I’m fairly technically competent and can code, as well as use Shortcuts on iOS. I don’t have an Apple developer license, though (which would give me access to HealthKit API which I don’t think would help).

Even if someone could point me to an API doc, I’d be grateful. I’m also fine to get data off the machine or over the datalink connection if that’s a better way to do it.

Thanks!
