Can I buy HEX on MetaMask?

Hello there, I have a question regarding the purchase of HEX tokens. I've been hearing a lot about HEX and its potential, and I'm interested in investing in it. However, I'm not sure if I can buy HEX directly on MetaMask, which is the crypto wallet I'm currently using. Can you please clarify if it's possible to buy HEX on MetaMask, and if not, what would be the most efficient way to go about acquiring HEX tokens? Thank you in advance for your help!
