var userProperties = PropertiesService.getUserProperties(); is not working properly for me?

Question

I am creating userproperties with PropertiesService, as

      var userProperties = PropertiesService.getUserProperties();

for storing use

According to the documentation at Properties Service - Saving Data:

"Script properties can also be saved via the script editor user interface by going to File > Project properties and selecting the Project properties tab. User properties and document properties cannot be set or viewed in the user interface."

I'm not sure what it means but I think it means that even if you are able to set the property using script, the value will not update if you view it in File > Project Properties > User Properties. But it doesn't mean that the property was not updated though. However, if it's a Script Property you set via script, the value will update in your view.

This I say because I tried it by setting it inside the doGet(). See the example below:

//Set properties as global variables
var userProperty = PropertiesService.getUserProperties();
var scriptProperty = PropertiesService.getScriptProperties(); 

function doGet() {

 userProperty.setProperty('uservar', 'Hello');
 scriptProperty.setProperty('scriptvar', 'World');

 Logger.log(userProperty.getProperty('uservar'));
 Logger.log(scriptProperty.getProperty('scriptvar'));

 return HtmlService.createTemplateFromFile('index').evaluate();
}

I did it inside doGet() so that I can check it simply by refreshing my WebApp page. Interestingly, the log shows the correct values (Hello, and World). But if I visit the File > Project Properties, only the Script Propery value was updated, the User Property remains the same as the original value I set it for.

Hope this helps.
