Hi! Best way to learn for me was to open similar maps and have a look at the triggers and locations, although I have never made maps.
Here’s a post with places where you can download maps from:
Beware, some maps are locked and you can’t open them in editors like SCMDraft2. Although, even if they are locked, some can be open in Chkdraft editor. I can’t recall if it opens them in edit or read only mode.
SCMDraft2:

Chkdraft:

There’s a new editor called ChkForge, but I’m not sure what it can do, as you would need to build the .exe yourself based on the code over here:

You could get help on staredit.net regarding map making. They also have a discord server.
You’re welcome!
