How to buy aero on Coinbase?

Excuse me, could you please explain the process of purchasing aero tokens on Coinbase in a step-by-step manner? I'm new to this platform and I'm having trouble navigating through the options. Is there a specific section or tab where I should be looking for aero? Also, do I need to verify my account before I can make a purchase? Additionally, what are the transaction fees associated with buying aero on Coinbase, and are there any limits to the amount I can buy? I'd appreciate any detailed guidance you can provide.
