Does Coinbase sell THETA?

Could you please clarify for me if Coinbase offers the sale of THETA tokens? I've been looking around for a reliable platform to purchase them, and Coinbase seems to be a popular choice among crypto enthusiasts. However, I'm unable to find a direct answer on their website or through their customer support. Would it be possible for you to shed some light on this matter? I'd greatly appreciate it if you could confirm whether or not Coinbase sells THETA, and if so, how I can proceed with the purchase. Thank you in advance for your assistance.
