Hi, a request was made to redirect the topic, currently in English, to French. Unfortunately we do not yet have forums for this language and all questions in this language are redirected to the universal language (English). The author of the question can request the redirection of a forum to one of the languages available on this platform. If you need further assistance, please send me a private message to discuss the matter.

Thank you for your understanding!

There is also a French forum if you prefer replies in French.
