How do I hide a dollar amount on Coinbase?

I'm curious about maintaining privacy when it comes to my financial transactions on Coinbase. Could you please explain the steps I need to take to hide a specific dollar amount from my account? Is there a feature within the platform that allows for this level of anonymity, or do I need to rely on external methods? Additionally, are there any potential risks or limitations I should be aware of when attempting to conceal dollar amounts on Coinbase?
