Not having a backlog is actually the thing I like about it. Discord (and Slack) have this thing where because there’s a backlog, people expect other people to have read everything. I prefer the experience where the assumption is that the people not in the room are assumed to have not seen a message. It makes it more unambiguously a synchronous experience, whereas Discord and Slack chat is pretty ambiguous as to whether it is synchronous or asynchronous.
