How do I buy crypto directly from my bank?

I'm curious about the process of purchasing cryptocurrency directly from my bank account. Could you explain the steps I need to take to make this happen? Is it a simple and straightforward process, or are there certain requirements or limitations I should be aware of? Also, how secure is this method of purchasing crypto, and are there any potential risks I should be mindful of? I'm looking to get started in the world of digital currencies and would appreciate any guidance you can provide.
