I have a Unity WebGL game uploaded. Is it possible to manually create a persistent directory in /idbfs inside IndexedDB?

Question

In the Unity project, I attached a script in an empty game object, and the code is demonstrated below: Is it possible to create a persistent directory myself?

public class TestScript : MonoBehaviour
{
    private void Start()
    {
        GetDefaultDirectory();
        CreateCustomDirectory();
    }

    // It returns "idbfs/" following with a random hash, such as "66ae5aa9b53f4a794ca331d30d2cb976".
    public void GetDefaultDirectory()
    {
        Debug.Log(Application.persistentDataPath);
    }

    // Manually create a directory
    // This can be created but will be flushed away after the page is reloaded.
    public void CreateCustomDirectory()
    {
#if UNITY_WEBGL
        Directory.CreateDirectory("idbfs/abcdef");
#endif
    }
}

And here's what the IndexedDB looks like. Only a random hash is shown here and my custom directory "idbfs/abcdef" won't be shown. But it did exist as I checked using Debug.Log.

In WebGL the path is passed through md5, that's why you can't recognize your directory name.
