If I wanted the full-fat Discord app (rather than a browser website or PWA, or a third-party client Discord will ban you over), I'd look into https://github.com/SpacingBat3/WebCord (which I think isn't detected and banned, but I cannot guarantee this or that they won't rewrite Discord to the point you can get banned for using it).
Do you have any cases of people getting banned over it? It would be scary, uBlock Origin blocks /api/*/science and it would be terrifying if running an adblocker could get you banned from Discord.
