No qualifying bean of type 'org.springframework.security.oauth2.client.registration.ClientRegistrationRepository' available

I am using Spring Boot 3.3.2 and try to integrate this library to avoid having to integrate with Okta for our integration tests.

I created this context initializer:

public class MockOAuth2ServerInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {

    @Override
    public void initialize(ConfigurableApplicationContext applicationContext) {
        var server = registerMockOAuth2Server(applicationContext);
        var baseUrl = server.baseUrl().toString().replaceAll("/$", "");

        String issuer = baseUrl + "/issuer1";
        TestPropertyValues
                .of(Map.of("okta.oauth2.issuer", issuer))
                .applyTo(applicationContext);
    }

    private MockOAuth2Server registerMockOAuth2Server(ConfigurableApplicationContext applicationContext) {
        var ssl = new Ssl();
        OAuth2Config config = new OAuth2Config(false, null, null, false, new OAuth2TokenProvider(), Collections.emptySet(), new MockWebServerWrapper(ssl));
        var server = new MockOAuth2Server(config);
        server.start();
        ((GenericApplicationContext) applicationContext).registerBean(MockOAuth2Server.class, () -> server);
        return server;
    }
}

And using it from my @SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT). However, I get this error at startup:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.security.oauth2.client.registration.ClientRegistrationRepository' available

Any idea how to fix this? Anybody else using this for integration testing when they use Okta?
