After entering the mountaintop, open the props bar. At the top of the screen, there are three bars: "Props", "Favorites", and "Facilities". Select favorites, choose a prisoner, and there is an option to allocate facilities at the bottom of the screen. Just assign the prisoner to the lounge.

So, the so-called embrace lounge is not an existing space.

Finally, I don't understand English, so I used translation software for this paragraph. So, if there are any difficult paragraphs to understand, please apologize.
