No config file when running on aternos

Title. The main page says it's directly in the .minecraft folder, but you can't access it on aternos, it would be better to have it in the config folder with everything else.

Start by locating the mod's configuration handling and the main-page text that says the file is in .minecraft. Check how the configuration path is selected when running on Aternos, then verify that the file is placed in the config folder with the other settings and that the usage instructions match.
