Adding a second icon to launch with a command line switch

Hi

I want to be able to run a portable packaged app (chrome) with a second icon (to sometimes launch with a command line switch).

running platform 16.0.1 on windows 8.1
latest chrome

the appinfo.ini file says:
[Format]
Type=PortableApps.comFormat
Version=3.5

I have tried to follow the example in the online manual here: https://portableapps.com/development/portableapps.com_format#appinfo
.. by defining Start1/Name1 and Start2/Name2, (no double quotes) but I do not see an additional icon anywhere

any pointers on what I am doing wrong ??
.. or on how to troubleshoot this?

thanks and regards
David
