You're probably talking about Rich Presence/Activity Privacy - note if you're using Wayland then it can only detect other X.org applications and not Wayland-based ones. So to maximise your security enable Wayland if it's not already default and prompt application developers to make their apps Wayland-compatible. You can check which of your currently running apps are using X11 by using `xlsclients`.
Discord has a setting (default = on) where it records everything you do on your machine after you install it. Blew my mind when I saw that!
Anyway I never used it for any written content, just a live voice group for a video game I used to play. Discord released a bunch of recorded chat logs after Unite The Right--they are completely compromised.
