How do I buy helium on Coinbase?

Could you please clarify the steps required to purchase helium on Coinbase? As a potential investor, I'm interested in learning about the process and ensuring I understand all the necessary details. What information do I need to provide during the setup process? How do I ensure my funds are secure during the transaction? And, is there a minimum purchase amount or any associated fees I should be aware of? Your guidance would be greatly appreciated.
