Issue with Klarna signin integration in my expo51 via native module

[mikeAdutskevich]

I'm having issues with Klarna signin integration in my expo(v51.0.0) project.
I use expo managed workflow with dev-builds.

The Klarnas' documentation:
https://docs.klarna.com/conversion-boosters/sign-in-with-klarna/integrate-sign-in-with-klarna/mobile-integration/

What I'm trying to do is to create a native module which will handle signin process.
I want to pass props to this native module and handle the response/errors of the signing proces. The main goal is to get idToken from the response.

I created a native module via npx create-expo-module klarna-auth. It creates a template for native module and example folder where I can test it with all predefined settings. The template works well.

Then I go to Android klarna integration and updated AndroidManifest.xml with:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools">
  <application>
    <activity android:name="com.klarna.mobile.sdk.activity.KlarnaRedirectReceiverActivity" android:exported="true" tools:node="replace">
      <intent-filter>
        <action android:name="android.intent.action.VIEW"/>
        <category android:name="android.intent.category.DEFAULT"/>
        <category android:name="android.intent.category.BROWSABLE"/>
        <data android:scheme="citygross" android:host="example"/>
      </intent-filter>
    </activity>
  </application>
</manifest>

This not causing errors at least now.

Then I defined an Event Handler. I took this code from the Klarna signIn docs as well:

package expo.modules.klarna

import expo.modules.kotlin.modules.Module
import expo.modules.kotlin.modules.ModuleDefinition

class KlarnaAuthModule : Module() {
  override fun definition() = ModuleDefinition {
    Name("KlarnaAuth")

    Function("getTheme") {
      return@Function "system"
    }
  }

  private val eventHandler = object : KlarnaEventHandler {
    override fun onEvent(klarnaComponent: KlarnaComponent, event: KlarnaProductEvent) {
      when(event.action) {
        KlarnaSignInEvent.USER_TAPPED_BUTTON -> {
          // User tapped the KlarnaSignInButton, auth process starting
        }
        KlarnaSignInEvent.USER_AUTH -> {
          // User completed interactive auth, tokens will be fetched
        }
        KlarnaSignInEvent.USER_CANCELLED -> {
          // User manually canceled sign in
        }
        KlarnaSignInEvent.SIGN_IN_TOKEN -> {
          // User is authorized. You can read the results      
          // in event.params attribute by casting it to the
          // KlarnaSignInToken model.

          val token = event.params[KlarnaSignInEvent.ParamKey.KlarnaSignInToken] as? KlarnaSignInToken
          val accessToken = token?.accessToken
          // Handle the access token
        }
      }
    }

    override fun onError(klarnaComponent: KlarnaComponent, error: KlarnaMobileSDKError) {
      // In case of any errors, check the 'error' parameter for more details, 
      // for example if the error is fatal or not.

      val errorMessage = error.message
      val isFatal = error.isFatal
      when(error.name) {         
        KlarnaSignInError.InvalidClientID -> {
          // The client ID value is invalid
        }
        KlarnaSignInError.InvalidScope -> {
          // The scope value is invalid
        }
        KlarnaSignInError.InvalidMarket -> {
          // The market value is invalid
        }
        KlarnaSignInError.InvalidCustomTabsReturnUrl -> {
          // The AndroidManifest needs to be set up for KlarnaCustomTabActivity
        }
        KlarnaSignInError.SignInFailed -> {
          // User authorization step failed
          val signInError = error.params[KlarnaSignInError.ParamKey.Error]
          val signInErrorDescription = error.params[KlarnaSignInError.ParamKey.ErrorDescription]
        }
        KlarnaSignInError.RenderButtonFailed -> {
          // Button failed to render
        }
        KlarnaSignInError.AlreadyInProgress -> {
          // Sign in is already in progress, user tap or signIn method call is ignored
        }
      }
    }
  }
}

Then I ran npm run build in native module folder('klarna-auth').
And then ran npx expo run:android in example folder to test the module.

And got the error:

Looks like i need link/install Klarna signin sdk, but I don't understand how to do it. Need your help.
