Can I send and receive from aliases using other apps like Apple Mail?

I could use help understanding how SimpleLogin aliases and reverse aliases work, as I think the latter might solve my question. But I can’t find mentions of using other apps with this system in the documentation so it gave me pause.

Basically I’m looking at switching to a Proton + SimpleLogin setup, but I mostly work on my iPad and iPhone with Apple Mail. I discovered the concept of reverse aliases here: https://simplelogin.io/docs/getting-started/send-email/

Would these help me email someone from an alias in Apple Mail? If so, I don’t understand the setup process:

• Create an alias
• Create a reverse alias
• Then what? How do I use that reverse/alias from Apple Mail to send a new email to someone? Or is this just not possible and I have to use the SimpleLogin app and/or Proton’s app?

Thanks for any help.
