Hi @Catherine3832 👋
Great question, and one that we get asked quite frequently here. @Joan2709 shared a fantastic answer on the thread How should I set up a listing to Co-host?
I've added Joan's answer below for you (but it's a great thread to read anyway) 👇
The listing should ALWAYS be setup under the Owner's profile/account. You setup your own, separate profile under your name.
After the listing is created, the owner invites you to be a full-access Co Host.
You can then be named as "Primary Host", but the actual Owner still shows as owner internally on the listing. Guests will see your name as Host and Owner as Co Host. If the Owner doesn't want to receive guest messages, they can turn OFF messages in their notification settings. You will need access to the Owner's account to setup scheduled messages and quick replies and create the Host Guidebook as these functions are only accessible through the Owner's account profile.
