如何继承付款屏幕并在 _finalizeValidation() 中添加验证

Question

I want to inherit _finalizeValidation() method from the paymentscreen of odoo15 in which I just want to add a condition that if the invoice is selected in the payment screen then the validate button will function and will move on to the receipt screen else will give a user error, and I am not getting a way to inherit and do so, Any help in this will be greatly appreciated

You can find an example in the pos_hr module where they inherit the _finalizeValidation function to set the employee on the current order:

odoo.define('pos_hr.PaymentScreen', function (require) {
    'use strict';

    const PaymentScreen = require('point_of_sale.PaymentScreen');
    const Registries = require('point_of_sale.Registries');

    const PosHrPaymentScreen = (PaymentScreen_) =>
          class extends PaymentScreen_ {
              async _finalizeValidation() {
                  this.currentOrder.employee = this.env.pos.get_cashier();
                  await super._finalizeValidation();
              }
          };

    Registries.Component.extend(PaymentScreen, PosHrPaymentScreen);

    return PaymentScreen;
});
