Can you buy crowns on Coinbase?

Excuse me, I was wondering if you could clarify something for me. I've been looking into purchasing crowns, but I'm not sure if Coinbase supports this type of transaction. Could you please tell me if it's possible to buy crowns on Coinbase, and if so, what steps would I need to take to complete the purchase? I'm relatively new to the world of cryptocurrency and would appreciate any guidance you can offer. Thank you in advance for your help.
