RNNordicDfu not included in NativeModules

[AshlandWest]

Line 2 of index.js: instantiates RNNordicDfu with const { RNNordicDfu } = NativeModules;
However, when running on Android (I have not tried IOS yet), NativeModules has no RNNordicDfu property at runtime, leading to an error on line 57 return RNNordicDfu.startDFU(upperDeviceAddress, deviceName, filePath); -> Cannot read property startDFU of undefined.

I am running React Native 0.70.8.
