How to buy ETH with Apple Pay?

I'm interested in purchasing ETH using Apple Pay. Could you please explain the process step by step? Firstly, which platforms or exchanges accept Apple Pay as a payment method for ETH? Secondly, what are the fees associated with using Apple Pay for this transaction? Also, are there any limits on the amount of ETH I can purchase through Apple Pay? Additionally, how secure is this method of payment, and are there any safety measures I should take? Finally, once I've purchased the ETH, how do I store it securely in a wallet? I'd appreciate it if you could provide detailed answers to these questions.
