I hope this helps . I have a problem calling to an array inside my object. , You can access the variables you want like this:
var item = additions_colorizing.items[5]; //This will get the 'mask' value
var item_color_names = additions_colorizing[item + '_color_names']; //This gets the 'mask_color_names' array
var item_color_codes = additions_colorizing[item + '_color_codes']; //This gets the 'mask_color_codes' array

How can I access an object array located inside of another object which is then inside a superclass array?

may help you . your Salesman constructor accepts an Order[] orders but it doesn't look like you keep a reference to it anywhere (unless you do that in getSalary or in the commented out portion).
You will need to add something like
public Order[] getOrders(){
    return orders;
}

public void setOrders(Order[] orders){
    this.orders=orders;
}
Salesman salesman = (Salesman) employees[i];
for (Order order : salesman.getOrders())
    System.out.println(order); // i don't know what fields order has!

will be helpful for those in need Here is a proof of concept of how it works. What makes you think it doesnt? (not trying to sound snarky) Are you referencing it correctly?
$obj = array(new stdClass());
$obj[0]->firstName = "NAME!";
var_dump($obj);
echo $obj[0]->firstName;
array(1) {
  [0]=>
  object(stdClass)#1 (1) {
    ["firstName"]=>
    string(5) "NAME!"
  }
}
NAME!

I wish did fix the issue. You can use $let with $arrayElemAt to handle two nesting levels but then you can add $project to get phone property.
db.collection.aggregate([
{
  $addFields: {
    selectedElement: {
        $let: {
           vars: {
              fstCustomer: { $arrayElemAt: [ '$customers', 0 ] }                
           },
           in: { $arrayElemAt: [ '$$fstCustomer.addresses', 0 ] }
        }
     }
  } 
},
{
  $project: {
    phone: "$selectedElement.phone"
  }
}
])
