How to unstake ankr?

Hello there, could you please elaborate on the process of unstaking ANKR tokens? I've heard that it's an important step for those looking to regain access to their staked funds, but I'm a bit unsure of the exact steps involved. Could you walk me through the process, including any potential fees or waiting periods that I should be aware of? Additionally, is there a specific timeline or requirement that needs to be met before I can initiate the unstaking process? Thank you in advance for your assistance.
