How to swap hETH to ETH?

Could you kindly explain the process of swapping hETH to ETH? I'm a bit unclear on the steps involved. Could you break it down for me? For instance, do I need to use a specific platform or exchange for the swap? Are there any fees associated with the transaction? Also, is it a quick and straightforward process, or does it involve more complex steps? I'd appreciate it if you could provide a detailed explanation of the entire swapping process. Thank you for your help!
