I have a setup that's probably more complicated than what you want, but
maybe you'll find something interesting in it. The problem is, you need
to somehow specify when or under what conditions you do away with the
opened windows and return to your org file or agenda. In my case, I use
the following to answer emails. When I open the link it stores the
current window configuration, and when the email is sent it triggers the
restore.

I believe I've confused myself slightly while trying to set up
interactive vs non-interactive versions, but so far I've never wanted to
use it non-interactively, so it works fine.
