Questions about Ubtech Jimu Robot TruckBots Kit

I was able to do some research and according to the manufacturer there is the "Jimu App" (with building instructions etc.), which can be downloaded from the App Store for iOS and the Play Store for Android. The app is available in the following languages: English, Danish, French, German, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Simplified Chinese, Spanish, Thai, Traditional Chinese, Turkish Unfortunately, I was unable to link to a PDF manual in French, as all possible instructions in PDF that I could find are in English.
