Some missing translation, even with Loco Translate

Hello,
first, very good work ! Your plugin is amazing ! Better than BBpress 😉
I did a french website about ChatGPT, but some sentences are still in english, I use Loco Translate on both Theme and your plugin, but for sure it has to be in the database I suppose, so how to modify them please ?

Thank you!
