Not able to open a process (Cocoa application) from Authorization Plugin

I am trying to open a cocoa GUI application from authorization plugin which runs during login. I have placed the application in /Library/Application Support/MyFolder/Example.app. I am using below environment and code to open the application.

Environment:

OSX: 10.14.5 (Mojave)

Xcode: 11.2.1

Swift: 4.2

Code:

let task = Process.init()
task.launchPath = "/Library/Application Support/MyFolder/Example.app/Contents/MacOS/Example"
task.arguments = ["Hi", "Hello"]   
task.launch()
task.waitUntilExit()

While the above code works perfectly fine when trying to open process from normal cocoa application it doesn't when I am trying the same from a bundle project which is used as an authorization plugin (https://developer.apple.com/documentation/security/authorization_plug-ins/using_authorization_plug-ins)
