2 Pages Share Same Comment Section

Hello everyone, I've been working on adding a bilingual feature to my website recently. So far, I haven't found a method that truly meets my needs. As a bilingual writer, I put a lot of effort into writing in both languages, so a simple website translation won't cut it. Moreover, I want to retain the comments from my readers on the same article, regardless of the language. The best solution I can think of is to have two pages share a single comment section. This way, I can create two separate pages for the same article in both languages, and readers from both language backgrounds can discuss in the same comment section. Does anyone know how to achieve this effect? I'd greatly appreciate any help. If you have the answer, I'd be delighted to treat you to a coffee.

Here is my website: lexing.me
As you can see, I have 2 blogs on my website, and I want them to share one same comment section.
By the way, can anyone tell me is it possible to hide one blog from anywhere on my website? I can use Javascript and HTML/CSS.
