i dont think there a "delete" button for it,
but i think staff would be able to do that for you.
there is the auto purge/delete option, where you simply do not log in.
that is the long way though, you have to wait like 60 days or so.
but its automatic anyway.
staff might be able to do it for you,
but you will need to wait for them to reply back.
you can try getting their attention faster on discord
