Problem: The rsconnect::purgeApp() function is designed to work exclusively with Shiny Servers. However, when a user attempts to use it for an app deployed on a Connect server, the logs provide inaccurate feedback.

Steps:

1. Deploy an app on Posti Connect
2. Navigate to IDE --> console
3. Run rsconnect::purgeApp( appName = "Your_app_name", server = "test_box", account = "Your_account_name")

Actual Result:
purging fails with the following error message

Purging application...
Error in client$purgeApplication(application$id) : 
  attempt to apply non-function

Expected Result:
Mention more accurate message eg: This method only works for ShinyApps server
