some base or api to create a discord bot? that does not need connection to the gamemode, a dynamic configuration bot

Well if you mean standalone bot you can write discord bots in most of the programming languages and there is even an app for creating bots on steam called "discord bot maker".

Just search on google "language name discord bot" and you will find tutorials/libraries etc.

This is the discord provided documentation, have a look around.
