I’m getting compilation errors with the code from the screenshot I shared. The issue is that `IConvaiNarrativeDesign` and `character.NarrativeDesign` are not being recognized.
Can you show me the correct namespace, required references, and a working code snippet for accessing `IConvaiNarrativeDesign` and `character.NarrativeDesign`?

There is no issue with the documentation code.
From what I can see, this looks more related to your Unity / C# scripting knowledge. Your IDE setup may not be configured correctly, so the required namespaces and references are not being detected or added automatically.
Since this is more on the Unity/C# scripting side, I recommend using an AI assistant or reviewing basic Unity scripting setup to help resolve the IDE/reference issue.
I’m sharing a screenshot below showing that the code compiles correctly on my side, along with the working code for reference.
```csharp
using Convai.Domain.Narrative;
using Convai.Runtime.Components;
using UnityEngine;
public class Test : MonoBehaviour
{
ConvaiCharacter character;
private void OnEnable()
{
character.NarrativeDesign.OnSectionChanged += HandleSectionChanged;
character.NarrativeDesign.OnSectionDataReceived += HandleSectionData;
}
private void OnDisable()
{
character.NarrativeDesign.OnSectionChanged -= HandleSectionChanged;
character.NarrativeDesign.OnSectionDataReceived -= HandleSectionData;
}
private void HandleSectionChanged(string previousId, string newId)
{
Debug.Log($"Section: {previousId} → {newId}");
}
private void HandleSectionData(NarrativeSectionData data)
{
Debug.Log($"Section ID: {data.SectionId}");
}
}
```

This looks like an issue related to your Unity account permissions or Unity’s package access system.
As a workaround, I uploaded the Unity package to [Google Drive](https://drive.google.com/file/d/11apSX-mCKkhCMR2aOzj66SSAWFimex11/view?usp=sharing). Please download it from there and import it into your project manually.
