How to connect with DynamoDB using WebIdentityTokenFileCredentialsProvider

I have the access key, secret key, region and DynamoDB endpoint through which I am able to connect to the database and I have kept the configurations in the application.properties file. Now the requirement is to not to keep the access key and secret keys in the application.properties file and follow the Web identity token from AWS STS. I have removed the access key and secret from the application.properties file and have the below configurations. When I start the application I am getting the below message

Consider defining a bean of type 'com.amazonaws.services.dynamodbv2.AmazonDynamoDB' in your configuration.

import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBMapperConfig;
import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBMapperConfig.DefaultTableNameResolver;
import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBMapperConfig.TableNameOverride;
import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBTypeConverterFactory;
import org.socialsignin.spring.data.dynamodb.repository.config.EnableDynamoDBRepositories;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import software.amazon.awssdk.auth.credentials.WebIdentityTokenFileCredentialsProvider;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.dynamodb.DynamoDbClient;

@Configuration
@EnableDynamoDBRepositories(dynamoDBMapperConfigRef = "dynamoDBMapperConfig", basePackages = "com.xyz.repository")
public class DynamoDBConfiguration {

  @Value("${aws.dynamodb.endpoint}")
  private String endpoint;

  @Value("${aws.region}")
  private String region;

  @Value("${aws.dynamodb.table.name}")
  private String tableName;

  @Bean
  public DynamoDBMapperConfig dynamoDBMapperConfig(TableNameOverride tableNameOverrider) {
    DynamoDBMapperConfig.Builder builder = new DynamoDBMapperConfig.Builder();
    builder.withTypeConverterFactory(DynamoDBTypeConverterFactory.standard());
    builder.withTableNameResolver(DefaultTableNameResolver.INSTANCE);
    builder.withTableNameOverride(tableNameOverrider());
    return builder.build();
  }

  @Bean
  public TableNameOverride tableNameOverrider() {
    return TableNameOverride.withTableNamePrefix(tableName);
  }

  @Bean
  public DynamoDbClient amazonDynamoDB() {
    return DynamoDbClient.builder()
        .region(Region.of(region))
        .credentialsProvider(WebIdentityTokenFileCredentialsProvider.create())
        .build();
  }

} 

In pom.xml I have the below dependency related to AWS.
