Launch DoubleCommander with two arguments for L-R panels

I do try to create a script that will launch the Double Commander app with two arguments for the Left and Right panel folders.

I do found here: Grasshopper-Python: How to start a CMD-Window and send commands to it with options some info on how to do something similar, and here: DC - Command Line some documentation on how to pass the arguments, but seems that I can’t get the syntax working. (5.1 KB)
