Does Coinbase accept arbitrum one?

Excuse me, I was wondering if I could get some clarification on something. I've been looking into Coinbase and their supported cryptocurrencies, and I've come across Arbitrum One. I'm curious to know if Coinbase accepts Arbitrum One as a tradable asset on their platform. I've done some research, but I haven't been able to find a definitive answer. Could you please provide some insight into whether or not Coinbase supports Arbitrum One and, if so, what the process is for trading it on their platform? Thank you for your time and assistance.
