Improvement in Testers Server

There is something which can be improved about testers server like when someone gets banned by mistake or any other issues and they get unbanned after that there's no way that they can get their old roles back for having access to few specific channels dbug bot doesn't work it says you have already passed the quiz and you can't also get roles from dbug bot command so you guys should add role persist feature like if someone gets banned and unbanned they'll get their roles and access back when they join back server again. Thank you
