Authentication and Access Control docs issue

[indexofmetals]

Hi, thank you for resolving my previous question so quickly. I have another one: when using the "isPerson" and "isAdminOrPerson" functions from the Auth and Access Control guide, I'm getting another type error:

Type '({ session, item }: { session?: Session; item: PersonData; }) => boolean' is not assignable to type 'ListItemAccessControl<"update", BaseListTypeInfo>'.
  Types of parameters '__0' and 'args' are incompatible.
    Type 'BaseAccessArgs<BaseListTypeInfo> & { operation: "update"; inputData: GraphQLInput; item: BaseItem; }' is not assignable to type '{ session?: Session | undefined; item: PersonData; }'.
      Types of property 'item' are incompatible.
        Type 'BaseItem' is not assignable to type 'PersonData'.ts(2322)

Is there some modifier I need to make on PersonData to make it compatible with BaseItem?
