Can I buy brett on MetaMask?

Could you please clarify for me? I'm a bit confused about something. I've been hearing a lot about MetaMask and cryptocurrencies, and I'm interested in purchasing some Brett tokens. But I'm not entirely sure if it's possible to buy Brett specifically through MetaMask. Could you tell me if it's actually feasible to do so? And if it is, could you also provide me with a brief step-by-step guide on how to proceed? I'd really appreciate your help in this matter. Thank you in advance for your time and assistance.
