Hi, how to remove icloud contacts from my child’s phone? They were added by default and I can only remove them one by one?

My child has an account via Family on iphone. In her contacts, she has access to all our icloud contacts. And then they have access to her. I want to remove the contacts from icloud on her phone, but the only way seems to be one by one, through screen time. On her phone we cannot access… how can I remove the icloud contacts to appear in her contacts? Thanks
