The Manage Users section will show all users that you create. Moreover, each user can use the
delete button to delete it. For the ACLs control, user can specify what topic should be limited. In
this case, we set up the publisher pub1 to write the critical topic. Additionally, we also allow the
subscribers sub1 and sub2 to read the critical topic. Thus, only the sub1 and sub2 can receive it
when pub1 sending the message.
