public void ShareAttachment(string title, string path, string mimeType, string filename)
{
    ShareSheet shareSheet = ShareSheet.CreateInstance();
    shareSheet.AddText(title);
    StartCoroutine(GetFileAsByteArray(path, (data) =>
    {
        shareSheet.AddAttachment(data, mimeType, filename);
        shareSheet.Show();
        
    }));
}

#region Helpers

{
    var sanitizedFilePath = GetSanitizedFilePath(filePath);
    UnityWebRequest request = UnityWebRequest.Get(sanitizedFilePath);
    yield return request.SendWebRequest();

    Debug.LogError("File path : " + sanitizedFilePath);
    if (request.isNetworkError || request.isHttpError)
    {
        Debug.LogError(request.error);
        callback?.Invoke(null);
    }
    else

    }
}

    if (filePath == null)
        return null;

    if (filePath.StartsWith("jar:") || filePath.StartsWith("file:"))
        return filePath;

    return Path.Combine("file://", filePath);

Usage

ShareAttachment("Sharing a zip file", Path.Combine(Application.streamingAssetsPath, "test.zip"), "application/zip", "test");

Note that the sharing content may or may not be compatible with the sharing service. Handling of the content is totally controlled by the service being used to share. Essential Kit only provides a way to share the content to the services and actual sharing is handled by the sharing service being used.
