Or, if one needs to provide an object instance directly:
```java
public class MyOllamaService{
public void chatWithAnnotatedTool(){
ollamaAPI.registerAnnotatedTools(new BackendService());
OllamaChatRequest requestModel = builder
.withMessage(OllamaChatMessageRole.USER,
"Compute the most important constant in the world using 5 digits")
.build();
OllamaChatResult chatResult = ollamaAPI.chat(requestModel);
}
}
```
The request should be the following:
