[FIXED] How to set Fedex Career in custom shipping module?

Issue

FedEx module's Carrier.php is extended in custom shipping module of our Magento store. I'm looking for a way to set FedEx carrier to "custom shipping" as below.

I don't seem to locate the method from the right class that returns the array of methods objects. Please help me find it. I tried to do it with $fedex_results->getAllRates() It isn't happening.

<?php

namespace Perfectmakeupmirrors\CustomShipping\Model\Carrier;

use Magento\Quote\Model\Quote\Address\RateRequest;
use Magento\Shipping\Model\Carrier\AbstractCarrier;
use Magento\Shipping\Model\Carrier\CarrierInterface;
use Perfectmakeupmirrors\PmmFedex\Model\PmmFedexCarrier;

/**
 * Custom shipping model
 */
class Customshipping extends AbstractCarrier implements CarrierInterface
{
    const FEDEX_METHODS = [
        'EUROPE_FIRST_INTERNATIONAL_PRIORITY' => 'Europe First Priority',
        'FEDEX_1_DAY_FREIGHT' => '1 Day Freight',
