UI narration option is missing in Chinese

UI narration is a feature designed for people with reading disabilities, but due to a bug, this narration option is not available in the Chinese version options bar.
You need to first change the game language to English, then go to the settings and find the last column “accessibility”, turn off the “UI Narration” at the bottom, and finally change the game language back to Chinese.
This bug was submitted on Steam as early as 2022, in the German/Portugal/French version, and has not been fixed, Over three years after release. It is really this complicated to fix? Or is it due to the negative work attitude of game developers?
