Can I buy Helium on Coinbase?

Could you please clarify if Coinbase, a popular cryptocurrency exchange platform, currently offers the option to purchase Helium tokens? I'm interested in diversifying my cryptocurrency portfolio and Helium seems like a promising investment, but I'm unsure if Coinbase supports its trading. It would be helpful to know if this functionality is available, or if there are any alternative platforms where I could safely and securely acquire Helium tokens. Thank you for your assistance in clarifying this matter.
