That option doesn't seem to work for me, but personally, if I need to use another discord account, I just use another Discord client, as Discord has 3 official ones (Stable, PTB, and Canary) <https://support.discord.com/hc/en-us/articles/360035675191-D...>, which all use their own account/data. For mobile, my OnePlus phone has a built in multi account app thing called Parallel Apps, and there are apps for it on Android.
