How to unstake Merlin?

Excuse me, could you please elaborate on the process of unstaking Merlin tokens? I'm a bit confused about the steps involved. Is there a specific timeframe I need to consider? Are there any fees associated with the unstaking process? Additionally, are there any potential risks or considerations I should be aware of before proceeding with the unstaking? I'd greatly appreciate a clear and concise explanation of the entire process. Thank you.
