How to read commandline settings of a job in deadline plugin

I’m writing a deadline monitor plugin to edit job commandline and I’m struggling to find a way to query command line settings from a job. How can I get and set it through the deadline API?

jobs = Scripting.MonitorUtils.GetSelectedJobs()
 
for job in jobs:
    print(job.GetJobInfoKeys())
    print(job.GetJobEnvironmentKeys())
    print(job.GetJobPluginInfoKeys())

all the above seem to be empty in my case.

thank you.
