What is Coinbase Pro fee?

Excuse me, could you please elaborate on the Coinbase Pro fee structure? I'm interested in understanding the different types of fees associated with using the platform, such as trading fees, deposit and withdrawal fees, and any potential additional charges. How does Coinbase Pro calculate these fees, and are there any ways to reduce or minimize them? I'm particularly interested in whether there are any fee discounts for high-volume traders or for users who hold a certain amount of Coinbase's native cryptocurrency. Thank you for your assistance.
