Newbie Q: Help with Qrexec & KDE Krunner Config

I’m trying to get KDE Krunner web shortcuts & web bookmarks to work. Problem has been getting Krunner to launch the appVM browser. I can’t figure out where/how to define it.

I’ve been drilling down on the Qubes docs, and it looks like qrexec might be the answer. But I have no clue what the command syntax would be.

Any experts want to help me out?

To wire up Dom0 Krunner web shortcuts to pipe request thru appVM: Work, browser:Firefox, what wold the command be?
