Do you have the Kotlin plugin in your build.gradle?

     dependencies {
         classpath("com.android.tools.build:gradle")
         classpath("com.facebook.react:react-native-gradle-plugin")
+        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.21")
     }

May I ask what you're using this module for? I'm just wondering if there are use cases outside of Microsoft that we haven't accounted for.

Thanks that was the missing piece so that the build can succeed. I'll can now take a look at implementation.
I'm looking for a solution to help login to Azure AD B2C. I've used @azure/msal-react in the past for react apps and found this library for using in react-native apps.

Is this particular library more intended for internal use?

@rnx-kit/react-native-auth mostly provides a JS interface for fetching an auth token. You typically implement your native module by extending this package. An example of this is @rnx-kit/react-native-test-app-msal which implements MSAL as the backend for this interface. We mostly use the latter package for our internal example apps though, so it's never been used in production. @rnx-kit/react-native-auth is used in production, but not as is.
