The entire history is not available, but the question is, how often is it really necessary to search that far back in the history? If something important happened, it would be worth saving it separately.
If the function of viewing the entire history is needed by everyone, and Discord provides it, then it can be used.
Just in case we can't manage without Discord, I registered a HeroesWorld server there; you can connect using this link: http://www.heroesworld.ru/discord
