Is arbitrum available on Coinbase?

Excuse me, could you clarify something for me? I've been hearing a lot about Arbitrum lately, and I'm interested in exploring it further. My question is, is Arbitrum currently available for trading or use on Coinbase, the popular cryptocurrency exchange platform? I'm trying to gauge the accessibility and convenience of getting started with Arbitrum, and Coinbase is usually my go-to for crypto transactions. Thanks in advance for your help!
