How to unstake on EtherFi?

Could you please explain, in a step-by-step manner, how one can effectively unstake their tokens on the EtherFi platform? I'm particularly interested in understanding the necessary prerequisites, any potential fees involved, and any safety considerations I should be aware of before proceeding. Also, is there a specific timeframe for the unstaking process, or can it be done instantly? I would greatly appreciate your guidance on this matter.
