Room Owners can designate other Room Members as a Host. Hosts are able to kick/ban other members, admit members from the waitlist, change the room name and background and set up integrations (basically, Hosts can do everything an Owner can do EXCEPT add additional Hosts or remove the Hosts).
You can make someone a Host by clicking on the Gear Icon and then going to the Member List. From there, hover over the person you want to make a Host and choose the Host Role.
