Add custom fields to Pow User Schema

[PriyavKaneria]

Hi,
First of all very nice and useful package!
I am a complete beginner and have just started to use Phoenix Liveview for a side project
I added email password Auth using this library easily, but now I want my Users table to have a few more columns like age, gender...
I went through the documentation but I was still a bit confused as to do I need to make a new Table and define create, update, delete functions for that user table to remain in sync with pow table or can I somehow add columns to Pow User table.

P.S. Also my goal is to have a live view of current loged in users
Thank you
