Currently there is no need for this as Telegram messages still work and Telegram channel network NEXTA (https://t.me/nexta_tv, from Belarusian word Нехта (someone), pronounced [ˈnʲexta](nyekhta), see https://be.wikipedia.org/wiki/Сцяпан_Аляксандравіч_Пуціла ) became the main tool for spreading news and coordination.
I've been wondering why it's called that for the last few days, thanks! Curiously, it's not mentioned on the Russian NEXTA wikipedia page.
