What it does
This class represents a return shipment request in Magento 2, used when customers need to send products back to the merchant.
It provides magic getter/setter methods to manage shipping details including shipper and recipient information, addresses, contact details, and package specifications.
Developers use this when implementing RMA (Return Merchandise Authorization) functionality or integrating with shipping carriers for return label generation.
