Magento 2.4.2: Type Error occurred when creating object: PerfectmakeupmirrorsCustomShippingModelCarrierCustomshipping,

I have a custom shipping module in which I am trying to instantiate FedEx carrier class to use its method as seen in the code below. But this throws an error:

Exception #0 (MagentoFrameworkExceptionRuntimeException): Type Error occurred when creating object: PerfectmakeupmirrorsCustomShippingModelCarrierCustomshipping, Argument 7 passed to PerfectmakeupmirrorsCustomShippingModelCarrierCustomshipping::__construct() must be an instance of MagentoFedexModelCarrier, array given, called in /home/magento/web/magento2.perfectmakeupmirrors.com/public_html/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 121

I don’t seem to find what is wrong with the way I am trying to call the method of FedEx.

namespace PerfectmakeupmirrorsCustomShippingModelCarrier;

use MagentoQuoteModelQuoteAddressRateRequest;
use MagentoShippingModelCarrierAbstractCarrier;
use MagentoShippingModelCarrierCarrierInterface;
use MagentoFedexModelCarrier;
