    if (obj == null)
        return item.thumbnail;

    var assetPath = SearchUtils.GetHierarchyAssetPath(obj, true);
    if (string.IsNullOrEmpty(assetPath))
        return item.thumbnail;

    if (options.HasFlag(FetchPreviewOptions.Large))
    {
        if (AssetPreview.GetAssetPreview(obj) is Texture2D tex)
            return tex;
    }
    return GetAssetPreviewFromPath(assetPath, size, options);
