hey I installed the new integration but did it all in one go (installed the new one in hacs, then deleted the old regular integration, then the old hacs integration but it said that I didn't delete the old one even though I did) so now after installing the new one it won't let my pc connect to the mqtt in ha, saying failed. (but the agent does show up as connected)
presumably the old one didn't get completely deleted? how do I do that manually? everything old is now gone in the UI
