Is arbitrum listed on Coinbase?

Could you please clarify for me if Arbitrum has been officially listed on the Coinbase platform? I've been following its development quite closely and I'm quite eager to know if Coinbase has added support for it. Would you happen to know the status of its listing on Coinbase, or any information about potential future listings? Additionally, could you provide any insights into the process Coinbase typically follows when listing new cryptocurrencies? Thank you in advance for your assistance in answering my query.
