To elaborate on my solution, which is simple but admittedly takes some tagging effort:
I tag every article with a language identifier, like English article, Spanish Article and so on.
Then, I can simply create emoji flagged language submenues linking to tag (i. e language) pages, i.e English, Spanish, German etc.
I can then choose from two variants:
1. the main menu entry being a general language placeholder – like the word “lingua” or “language – with the language options in the submenues.
2. the main menu entry being an indicator (and link) to the main language, e.g. English – again with he language options in the submenues.
It’s kind of hacky and again – takes some tagging effort – but then again, it’s a solution that works right away without the devs even considering official multi-language support for posts – which would presumably require some kind of tagging action anyway.
