How to import a bean which comes from a configuration bean conditional on another class?

I'm using a 3rd party dependency in my Spring Boot project (version 2.6.3) which has the following classes:

@ConditionalOnProperty(prefix = "spring.cloud.vault", name = "enabled", matchIfMissing = true)
@AutoConfigureAfter(ApacheHttpClientAutoConfiguration.class)
@Configuration
public class VaultServiceAutoConfiguration {
    // ...
}


@Configuration
@EnableConfigurationProperties({VaultServiceProperties.class})
@ConditionalOnBean(VaultServiceAutoConfiguration.class)
public class VaultServiceFacadeConfiguration {
  private final VaultServiceProperties vaultServiceProperties;

  @Autowired
  public VaultServiceFacadeConfiguration(VaultServiceProperties properties) {
    this.vaultServiceProperties = properties;
  }

  @Bean
  @ConditionalOnMissingBean(VaultServiceFacade.class)
  public VaultServiceFacade vaultServiceFacade(
      @Qualifier("runtime") VaultServiceTemplate vaultServiceTemplate) {
        // ...
  }
}

I set spring.cloud.vault.enabled=true in my bootstrap.yml.

In my project I import the dependency and created a component class:

@Component
public class MyVault {
    private VaultServiceFacade vaultServiceFacade;

    public MyVault(VaultServiceFacade vaultServiceFacade) {
        this.vaultServiceFacade = vaultServiceFacade;
    }
}

in order to use VaultServiceFacade bean which provides methods to interact with Hashicorp Vault instance. The problem is that I get this error: No qualifying bean of type 'other.package.VaultServiceFacade' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

I don't understand why I get his error because my main class is annotated with @SpringBootApplication so that auto-configuration is enabled. In addition if I try to inject VaultServiceAutoConfiguration bean it works:

@Component
public class MyVault {
    private VaultServiceAutoConfiguration v;

    public MyVault(VaultServiceAutoConfiguration v) {
        this.v = v;
    }
}

EDIT: I did notice that the dependency has a file spring.factories with the following code:

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
  other.package.VaultServiceAutoConfiguration

So maybe only VaultServiceAutoConfiguration is "whitelisted" for auto-configuration, so I need to understand how to allow other beans from other.package to be injected in my project.

EDIT2: I managed to get this working by adding @ComponentScan on the MyVault class:

@ComponentScan("other.package")
@Component
public class MyVault {
    private VaultServiceFacade vaultServiceFacade;

    public MyVault(VaultServiceFacade vaultServiceFacade) {
        this.vaultServiceFacade = vaultServiceFacade;
    }
}

I still don't understand why the ComponentScan works only on when added to MyVault class but is if I scan for this package from main it class it doesn't work:

@SpringBootApplication(scanBasePackages = {"other.package"})
public class Application {

  // ...
}
