Metabox for User Profile Page (User Meta)... possible?

[ruturajpatki]

In one of my recent projects, I needed to add some extra fields to User Profile Page. I couldn't achieve this with Option Tree and truly running out of time, so I had to switch to CMB2 for metabox functionality.

Now that the project is over and delivered, I'm curious to know if this functionality is possible with Option Tree; and if so, how to add Meta Box to User Profile page? How to read the value in theme?
