Is Alice on Coinbase?

Could you please clarify if Alice is indeed a registered user on the Coinbase platform? I'm inquiring as I'm trying to locate her profile or transaction history for a specific reason. If Alice is indeed a user, is there a way to verify her identity or check if she's actively using her account? Additionally, could you provide any guidance on the steps required to reach out to her directly if needed, assuming privacy policies and regulations are adhered to? Thank you in advance for your assistance.
