missing the option "manage with parental controls" while creating dedicated account for child

I am using Catalina and when I try to create a new account for my child, I am missing the option "manage with parental controls" ... I get "Administrator", "Standard", "Sharing Only" and "Group" as the only options in the New Account field. Can someone tell me how to create a child account with these options or why am I missing the "Manage with Parental Controls" option?
