OK, I'm sorry. Maybe my understanding was different. Translations issues :-) Tell me, or feel free to delete my messages for a cleaner conversation, no problem ;-)
Just to finish, ENV file is not a great solution. If I want to modify a token from the app frontend, i have to re-generate the env file (might be a security issue, and if something goes wrong with this, the whole app shuts down). So, config folder is not a good place (your topic), env file isn't great, and there is no way I will use a db for this :-) Conclusion... JSON seems to be my only friend and I am gonna have to keep this unused "Config" folder in my app :-)
