Formal form in foreign languages in GPT-3

I have one auto blog AI-site in German and one in French. But I need formal forms like the German "Sie" oder the French "Vous". Anyone got a good prompt for this? Tried everything, but it always uses "Du" (German) and "Tu" (French).

Here you go:

make sure you use the plural form (vous) instead of the singular form (tu)



I haven't tried with German, but it might work in the same way.
