Is the sandbox available on Coinbase?

Excuse me, I was wondering if I could clarify something regarding Coinbase. Specifically, I'm interested in the availability of a sandbox environment on the platform. Does Coinbase currently offer a sandbox or testing feature that allows users to simulate trades and transactions without the risk of using real cryptocurrency? I understand that this type of feature can be invaluable for learning and practicing, so I'm curious if it's a part of the Coinbase offering. Thank you for your time and assistance in answering my question.
