Converting UX to polymer 3

Still here? If you're ready for yet another serving, I admire your appetite! In my previous articles, we explored the concepts, built a simple UX application, and extended it with new fields, buttons, dialogs, toasts, and ways to manipulate records. This time, we'll discuss how to convert your custom UX apps from the Polymer Version 1 standard to the Polymer Version 3 standard.

Tip: What is UX? The standard definition of UX is user experience. But for simplicity, I'll refer to the Maximo® Real Estate and Facilities UX framework as UX.
