How do I update my Coinbase mobile app?

Could you please explain the process of updating my Coinbase mobile application? I've noticed that there's an available update, but I'm not quite sure how to proceed. Is it necessary to uninstall the current version first? Or can I simply update it in-app? Also, will updating affect any of my current transactions or wallet balances? It would be great if you could provide step-by-step instructions on how to safely and effectively update my Coinbase app. Thank you in advance for your assistance.
