I'm creating a chess course in the Odoo eLearning module. I plan to upload videos for lessons, and instead of a quiz at the end of each lesson, I want to embed a fully functional chessboard using custom HTML code.

In the Odoo tutorial, I saw an option to add a webpage to a course, but I cannot find this option in my current Odoo database. My goal is to replace the quiz with an embedded chessboard using HTML.

Could someone guide me on:

1. How to embed custom HTML (the chessboard code) in an eLearning course?
2. Why I might not be seeing the "Add Webpage" option in my database? Is there a specific module or permission I need to enable?

Any help would be greatly appreciated!
