Using Unimodules in iOS Extension

I have a basic Expo app I ejected in order to create an AutoFill extension in iOS.
Part of the functionality requires using ExpoSecureStore (a Unimodule) which works fine from the main app, but when using from the extension says that ExpoSecureStore is not defined. I’m fairly certain this is due to Unimodules not being properly linked in the extension.

I’ve tried modifying my view controller to mimic the app’s AppDelegate.m file, to no avail.

All the dependencies are properly linked, and I can run the JS code in the extension. It’s just the Unimodules that don’t seem to work. I’ve run pod install and linked binaries with libraries.

Anyone have any experience getting Unimodules to work in iOS extensions?
