How to buy Oasis Network on Coinbase?

Could you elaborate on the steps required to purchase Oasis Network tokens on the Coinbase platform? I'm a beginner in the world of cryptocurrencies and would appreciate a step-by-step guide. Specifically, I'm interested in knowing if I need to set up a specific wallet for Oasis Network, whether there are any fees involved in the transaction, and if there are any specific requirements or verifications I need to complete before making the purchase. Additionally, I'd like to understand the overall process Flow and any potential risks or considerations I should be aware of. Thank you for your assistance.
