Because the XNode features of LabVIEW require a special license by NI, these properties and methods won't be listed on the XNode, or XNode Library class, but these functions do work. I made a post about this a while ago, and showed how to create these functions in vanilla LabVIEW if you use scripting, or use the QuickDrop function and know the name of the property or method you want. The code I posted also can create a new VI, or place the hidden property or method in your clipboard. I also posted a VI with all the properties and methods that scripting can make which you can use and copy into a VI and use.
