New to Quest: switch to child account

I purchased the Quest 3 for my 10-year-old daughter for Christmas and have been trying to set it up for her. I created an account in the Meta Family Center, but my daughter does not have a Meta account yet. When I access the VR headset, I see an option to add an account, so I entered my daughter's email (which she is not currently using; I created it to reserve her full name before anyone else could claim it). However, when I receive the email, it prompts me to create a Meta account for her, which I prefer not to do.

While reading the setup articles, I noticed they are unclear and do not mention the need to create a Meta account for a child. How can I switch the VR headset to her account and manage it through the Family Center without creating a separate Meta account for her?
