How can I fetch the name of the User Source configured in my Ignition project properties using a script?

[Cose_Peter1]

I once had the requirement to add users to the default userSource and this is how I did it.
Not sure if we can just get the name of the userSource.

Get the User Source the project is set to in perspective

Parameters String userSource - The user source to add a user to. If set to an empty string, the function will attempt to use the project’s default user source (if called from a project).
