@Haopeng138 Thank you so much. They are still part of the library. I forgot to update them since I moved the asynchronous versions years ago. I really appreciate it. I have to say that I feel weak in the documentation. That's why I spent a lot of time on it last week. Now, when you mention some of the things in the example folder, I realize I forgot about the example folder. I'll try to update it more. If you find anything else, please help and support. Thank you. I will add your name to contributor name as well.
