Does Coinbase sell USDC?

Excuse me, could you please clarify something for me regarding Coinbase? I'm curious if Coinbase, as a leading cryptocurrency exchange platform, offers the option to buy or sell USDC, the stablecoin that's designed to maintain a 1:1 ratio with the US dollar? I'm interested in understanding the extent of their services, especially in terms of supporting various digital assets like stablecoins. Could you kindly elaborate on whether Coinbase facilitates the trading of USDC and the steps involved, if any? Thank you for your time and assistance.
