Survey Creator Custom Options - Cannot show Help Description for a custom Boolean option

[JaneSjs]

I created a custom Boolean property and want to show help description for it. However, the following code doesn't work - a help icon isn't shown for a custom Boolean property.

Survey.Serializer.addProperty(
  "survey", 
   {
     name: "sampleProp:boolean",
     category: "Watermark"
  }
);
const translations = SurveyCreator.localization.getLocale("");
debugger;
translations.pehelp.sampleProp = "Sample tip here";
