How long does it take to unstake from Lido?

Could you please enlighten me on the process of unstaking from Lido? I'm curious to know how long it typically takes to complete this procedure. Is it a quick and straightforward task, or does it involve a series of steps that may take some time? Could there be any delays or factors that might prolong the unstaking process? It would be greatly appreciated if you could provide me with a detailed answer to this question. Thank you in advance for your assistance.
