How do I re-verify my identity on Coinbase?

Hello, I'm having some trouble re-verifying my identity on Coinbase. Could you please provide me with a step-by-step guide on how to do this? I've heard that identity verification is important for security and compliance, so I'd like to ensure my account is fully up to date. Specifically, I'm not sure where to find the option to initiate the verification process, or what kind of documents I'll need to provide. Additionally, I'm wondering if there's a specific time frame in which I need to complete this process to avoid any potential issues with my account. Thank you for your assistance.
