How to Launch Any Chromium Application From Command Line, like Camera app

[Ust chromium]

Hi,  I am facing the problem of launching chromium application directly from the shell command line (Ctrl+Alt+T) in Chromium OS (strago / rambi ) which  is installed on Target board as Braswell /Skylake. 

I am looking for solution to automate any app launch by using CLI and python or autotest test suite. For instance, I would like to launch a application as Camera without UI or user intervention.

So far I have tried the following options. However, it could not worked. 

  1. /opt/google/chrome/chrome --app-id <app id>   from shell command line (Ctrl+Alt+T).  

     Command has executed. However, App has not launched and has not thrown any error message.

   2.  /opt/google/chrome/chrome  --profile-directory=Default --app-id=<app id> from shell command line.

      Command has executed. However, App has not launched and has not thrown any error message.

I highly appreciates suggestion or solution to this problem.

Thank you.
