When can i unstake Ethereum lido?

Could you please elaborate on when I can unstake my Ethereum Lido? I'm quite interested in understanding the timing and process involved in withdrawing my staked tokens. Is there a specific period after staking that I need to wait before I can unstake? Or are there any conditions or requirements that need to be met before I can proceed with the unstaking process? It would be helpful if you could provide some clarity on this matter.
