How to use WorkDocsClient with access token from redirect ur

Hello,

I'm trying to make an Android App to access WorkDocs Site, It's a user level application, not administrative application. I created my WorkDocs site and my application, so I got the application_id.

Using GET request with application_id, I obtained the access token

GET https://auth.amazonworkdocs.com/oauth?app_id=my-app-id&auth_type=ImplicitGrant&redirect_uri=https://myapp.com/callback

And then, I'm trying to do something.

The error occurs when workdocsClient is created.

    val credentialsProvider = AnonymousCredentialsProvider.create()
    val workDocsClient = WorkDocsClient.builder()
        .region(region)
        .credentialsProvider(credentialsProvider)
        .build() <-- ERROR

    val request = DescribeFolderContentsRequest.builder()
        .folderId(folderId)
        .authenticationToken(accessToken)
        .build()

    val result = workDocsClient.describeFolderContents(request)

    for (folder in result.folders()) {
        System.out.printf("Folder name=%s, Id=%s \n", folder.name(), folder.id())
    }

java.lang.VerifyError: Verifier rejected class software.amazon.awssdk.http.apache.ApacheHttpClient: void software.amazon.awssdk.http.apache.ApacheHttpClient.$r8$lambda$~~~~~

build.gradle dependecy is below:

dependencies {
    implementation 'androidx.core:core-ktx:1.7.0'
    implementation 'androidx.appcompat:appcompat:1.6.1'
    implementation 'com.google.android.material:material:1.9.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'

    implementation 'software.amazon.awssdk:workdocs'
    coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.1.5'
}

Please let me know how I can resolve this error or what I should check. Thank you for your interest and reading.
