How to unwrap cbETH on Coinbase?

Could you please elaborate on the process of unwrapping cbETH on Coinbase? I'm a bit unfamiliar with the concept and would appreciate a step-by-step guide. As I understand, cbETH is a wrapped version of Ethereum, specifically designed for trading on Coinbase's platform. But how do I convert it back to its original, unwrapped form? Is there a specific function or tool within Coinbase that facilitates this process? Additionally, are there any fees or limitations associated with unwrapping cbETH? Your insights would be greatly appreciated.
