Maybe you try to directly contact the team at the project's telegram channel at https://t.me/ehfirstgroup so that your concerns will be addressed immediately.
True most of the project are active in telegram, the admins , community manager and staff are more active in telegram. First it was slack then discord and now telegram
Discord is probably the best of the three but it is not so widespread like Telegram.
If you want fast contact with admins, then telegram is much better option but discord is more readable. Right now its impossible to stay of social media since people tend to trust projects more if they are represented on many social medias.
