Is ARB listed on Coinbase?

Excuse me, could you please clarify whether ARB, or the cryptocurrency in question, is indeed listed for trading on the Coinbase platform? I've been doing some research on potential investments in the crypto space and ARB has caught my eye. However, I've been unable to find a definitive answer on whether or not it's available for purchase on Coinbase. I understand that Coinbase is a major cryptocurrency exchange and its listing status for various cryptos is of utmost importance for investors. Your insight would be greatly appreciated.
