Can I buy ash on Coinbase?

Excuse me, could you clarify something for me, please? I'm interested in purchasing a certain asset on Coinbase, but I'm not entirely sure if it's possible. Specifically, I'm wondering if I can buy ash on the platform. I understand that Coinbase is a popular and reputable exchange for buying and selling cryptocurrencies, but I'm unsure if ash is listed as an available asset. Could you tell me if it's possible to buy ash on Coinbase, and if so, how I might go about doing that? Thank you for your time and assistance.
