How to get staked ETH out of Coinbase?

I'm curious about the process of retrieving staked Ethereum (ETH) from Coinbase. Could you please elaborate on the steps involved? I understand that staking ETH involves locking up coins to support the network and earn rewards, but what's the process to withdraw those coins once they're no longer being staked? Are there any specific requirements or fees associated with the withdrawal? Additionally, how long does the withdrawal process typically take, and is there any risk involved in the transaction? Clarifying these details would greatly assist me in managing my crypto assets.
