How Do I Launch VSH with Commandline Arguments?

I am adding my emulators to Playnite so I can more easily launch and manage stuff from my couch using a controller. I know I can enter into the VSH through the application GUI, but how do I launch it using commandline arguments? I tried using the file path

Code:

RCPS3\dev_flash\vsh\module\vsh.self

as the commandline argument, but it just said invalid file.
