Create user on Master does not create it on Slave

We have mysql replication set between two aurora clusters. Everything looks good and the replication is working well. However, I created a few hours ago a user on the master and I still don't see it on the slave. I see that Aurora excluding mysql schema which might be the issue. But I don't know if I should create the user myself or what.
