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.

Thank you, it's good to know, but is it supported on mobile apps? I think it's more problem on mobile, because on desktop, mostly Discord can be used in browser so Chrome profile or Firefox container works.

Oh, I don't really use it on mobile :( . It's on my work laptop where like you I keep my private and work accounts separate :) . You could certainly do it with multicontainer on android firefox but not on iphone :( . I suppose you could install multiple browsers in that case but again I only need in emergency situations on my phone.
