HTML5 in UE4 (4.26.2) - UE5 (5.0)

I have gone to the official page Developing HTML5 Projects | Unreal Engine Documentation
and comments:
“As of Unreal Engine 4.24, support for the HTML5 platform has been migrated out of the engine to a public Platform Extension that can be maintained and improved by community members. Documentation for the HTML5 Platform Extension is hosted alongside the GitHub repository.”
GitHub - UnrealEngineHTML5/Documentation

How does this extension work? I’ve tried to implement it as a plugin and it doesn’t work.

I am using version 4.26.2

Today I was testing the UE5 version. I would like to know how to also implement html5 in UE5.

Is there a way to implement the HTML5 SDK? or some HTML5 SDK (which is always up to date) in UE?
