Thank you, I am a biginner. How I can add that extension. Kodular is asking for file or url.

First, download the extension (.aix) file from the post, then import it here.

You first should get more experience in developing with Kodular before using that extension.

See the App Inventor Extensions document about how to use an App Inventor Extension

A very good way to learn App Inventor or Kodular is to read the free Inventor’s Manual here in the AI2 free online eBook App Inventor 2 Book: Create Your Own Android Apps … the links are at the bottom of the Web page. The book ‘teaches’ users how to program with AI2 blocks.

There is a free programming course here Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps

How to do a lot of basic things with App Inventor are described here: How do you...? .

Also do the tutorials Our Tutorials! to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor
