How do I Unstake my TRON?

Hello there, I'm curious about the process of unstaking my TRON tokens. Could you please elaborate on the steps involved in unstaking TRON? Is there a specific timeline or period I need to wait before my tokens become available for withdrawal or trading? Additionally, are there any fees associated with the unstaking process? It would be great if you could provide a comprehensive overview of the entire unstaking process. Thanks in advance!
