Does Hermes in React Native Windows v0.73 (with Fabric disabled) support Native Modules made in Paper?

[shirakaba]

I've made a Paper native module named ReactNativeAppAuthJs following the old RNW 0.70 guide and the sample Paper C++ module.

The problem I'm finding is that my native module only registers itself onto the NativeModules object when Remote Debugging is turned on (i.e. when executing JS in Chrome). If I turn off Remote Debugging, NativeModules.ReactNativeAppAuthJs returns null.

Does Hermes for RNW not support Paper native modules or something? Is there any way to get them working without updating React Native? Just that I'd like to avoid updating if I can as it may cost a lot of time, particularly as I'd have to update React Native macOS and I assume I'd have migrate all my native modules to Fabric.

Possibly related:

• NativeModules not working in release .72 #12521 (however, my module isn't a TurboModule to my understanding, so I'm not sure it applies?)

Very surprised to find that the suggestion in #12521 fixes it:

- import { NativeModules } from "react-native";
- NativeModules.ReactNativeAppAuthJs.authenticate(/* ... */);
+ import { TurboModuleRegistry } from "react-native";
+ TurboModuleRegistry.get("ReactNativeAppAuthJs").authenticate(/* ... */);

My module isn't a TurboModule (there's no codegen, for example) so I'm surprised to find that it's registered into the TurboModuleRegistry.
