How to convert link on HTML file for offline using?

this is my first post here. I want to ask something.

So I've been downloading a website from wayback machine using this great tool https://github.com/hartator/wayback-machine-downloader

All download is good, but when I open it turns out all the link inside the HTML file is still direct to online url link such as: "https://www.somedomain.com/SOMEDIRECTORY"

There's 1.3GB file total size.

I've tried to google it but it seems there's not much information about this tool.

Is there any way to convert all those links into the right file directory within the folder, because all folder is already set as the tool place it.

Thanks by the way for your time :)
