Family Sharing Contacts

I have Family Sharing set up which includes my kids.

I don't want to give them access to my Contacts.

But I do want to retain my Contacts across the device that I use

(i.e. iCloud prefs)

The options for sharing in the iOS iCloud UI are

Purchase

Apple Music

iCloud Storage

Location

Screen Time

Any thoughts on if there is an auto-Apple way or do I have to manually

create a seperate Family Contact book?

Thanks

John
