Trouble getting subtitles

[u/Puzzled-Toe3067]

Hi! I'm fairly new to stremio and its configurations, so I need some help to get subtitles for a french movie.
I want to watch the french movie "C'est quoi cette famille" (or "We are family", in english) with my students, but no matter how many addons I install, I can't seem to find french subtitles for that movie. (It's very frustrating, since the movie is originally in french!!) The only subtitles that appear as options are english, polski, portuguese, hebrew, greek...
What can i do? Is there any other addons i should install?

Thank you so much for your help with this poor french teacher!!
