How do I run a Bridge jsx script from the command line

I know that using (e.g.) After effects I can type something like:

afterfx.exe -r "c:\myDocuments\Scripts\Script Name with Spaces.jsx"

to run the Name With Spaces jsx file from the command line.

However, it doesn't seem to work for Bridge:

"C:/Program Files/Adobe/Adobe Bridge CC 2019/Bridge.exe" - r "C:/Users/UserName/Documents/temp/sample_com.jsx"

just opens bridge and doesn't call my script.

How do I run the sample_com.jsx from the command line?

Thanks
