What is the best way to accomplish the following:

Upon user login:
Launch Microsoft Edge with a particular URL, on a SPECIFIC monitor (by number), flagged for full screen (on that specific monitor)

(repeat the above with different urls, five more times, for displays on seven different monitors, all on the same machine, of course)

I've spent some time in the user manual but the "trigger" and "window position profiles" don't seem to make sense to me to accomplish what I actually want.

Thanks in advance. I have the trial version installed right now for 28 more days.
