Can you buy HBAR on Coinbase?

Could you please clarify for me, is it possible to purchase HBAR tokens directly through the Coinbase platform? I've been exploring various cryptocurrency exchanges, and I'm particularly interested in adding HBAR to my portfolio. However, I'm not entirely sure if Coinbase supports this particular cryptocurrency. Could you help me understand if Coinbase offers the option to buy HBAR, and if so, what are the steps involved in the process? Additionally, I'm also curious about any potential fees or limitations that might apply when purchasing HBAR on Coinbase. Thank you for your assistance.
