1. **Implement `CrawlerClient`**:
```java
public class MyClient extends AbstractCrawlerClient {
    @Override
    public ResponseData execute(RequestData request) { /* ... */ }

    @Override
    public void close() { /* cleanup */ }
}
```

2. **Register in DI config** (`crawler.xml`):
```xml
<component name="myClient" class="...MyClient" instance="singleton"/>
```

3. **Add to factory**:
```java

	pCfg := r.arnProviderCfgsMap[arn]
	if pCfg.JWKS.URL == nil || pCfg.JWKS.URL.String() == "" {
		return nil
	}

	// Add client secret for the client ID for HMAC based signature.
	r.pubKeys.add(pCfg.ClientID, []byte(pCfg.ClientSecret))

	client := &http.Client{
		Transport: r.transport,
	}

	resp, err := client.Get(pCfg.JWKS.URL.String())
	if err != nil {
		return err
	}
	defer r.closeRespFn(resp.Body)

	return ErrNotImplemented
}

// LoginWithClientID is implemented by Keycloak service account support
func (k *KeycloakProvider) LoginWithClientID(clientID, clientSecret string) error {
	values := url.Values{}
