How do I launch Glip.exe and open a chat with a specific user?

We have an application that interacts with RC phone and Glip. We are implementing a connection with RingCentral now in place of Cisco Finesse. One of the features allows user to launch the chat application with a chat started for a specific user.

I was able to modify windows registry to open Glip.exe as a default application:

C:Usersfname.lnameAppDataLocalGlipUpdate.exe --processStart Glip.exe

But how do I submit a parameter for the chat? Probably an account Id?
