We are terribly sorry to keep you waiting for 2 month without repsonse due to us being in a difficult situation since the translation is currently being done bu one of our member as well at the time of the creation of this issue. A good news is that the translation is ready and will be merged. Regardless, your contribution still means a lot to us and we thank you a lot. ❤️
