adding boolean to disable automated update of chat ids

[Arthessia]

During my server lifecycle, I noticed sometimes some new chat ids configured during the startup.

the plugin was taking some other chat ids (not needed) and automatically configure them as direct targets of notifications.

I wanted to disable that "bug".

So the use case of disabling this would be to prevent the bot sending updates to user chats, i.e. when you only want to have the bot in a group chat?
