Can you buy mantra on Coinbase?

Excuse me, I'm a bit confused about the availability of Mantra on Coinbase. I've been looking to invest in this particular cryptocurrency and was wondering if Coinbase supports its trading. Could you please clarify if I can buy Mantra directly through Coinbase or if I need to use another platform? Additionally, if Coinbase doesn't offer Mantra, could you recommend any reliable alternatives where I could safely purchase it? Thank you in advance for your help.
