How do I use Bitcoin ATM first time?

Hello there, I'm curious about how to use a Bitcoin ATM for the very first time. Could you please guide me through the process step-by-step? I'm not very familiar with cryptocurrencies or ATMs in general, so I'd appreciate it if you could explain it in a simple and clear manner. What are the necessary steps I need to take? What kind of information do I need to provide? And is there anything I should be aware of before using a Bitcoin ATM for the first time? Thanks in advance for your help!
