Member "push" not found or not visible after argument-dependent lookup - ethereum

Question

Issue
There seems to be some issue with this line here family.People.push(people[x]);
I keep getting Member "push" not found or not visible after argument-dependent lookup when I try to compile with brownie.
What have I tried
I saw a few SO posts with similar exceptions but it was related to type casting. I did try to cast my incoming array to its type but it just resulted in more exceptions.
Code
pragma solidity ^0.8.9;
contract Person{
string public FirstName;
string public LastName;
}
contract Family{
Person[] public People;
}
contract FamilyManager{
Family[] Families;
function AddFamily(Person[] memory people) public {
Family family = new Family();
for(uint x; x < people.length; x++){
family.People.push(people[x]);
}
Families.push(family);
}
function GetFamilies() public view returns (Family[] memory){
return Families;
}
}
Can anyone spot what I'm doing wrong here or link to an article that can lead to an answer?

I think it is related to access modifiers. Using the public modifier for your array only generates the getter function for it and not the setter.
As a result, you cannot directly push to an array from another contract. I created a public function to add elements to the array as follows:
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.9;
contract Person{
string public FirstName;
string public LastName;
}
contract Family{
Person[] public People;
function addPerson(Person person) public {
People.push(person);
}
}
contract FamilyManager{
Family[] Families;
function AddFamily(Person[] memory people) public {
Family family = new Family();
for(uint x; x < people.length; x++) {
family.addPerson(people[x]);
}
Families.push(family);
}
function GetFamilies() public view returns (Family[] memory){
return Families;
}
}
