[Community Auth] How to add customs fields?

Hi thanks for the info, i try all the steps in the link but we have an error
Undefined property: stdClass::$first_name community auth
How can fix that?
Can directly add customs fields to the Users table?

Yes, you can do whatever you want. Community Auth has provided the foundation, but does not attempt to be the architect. To master Community Auth usage, you're going to need to read through the entire documentation and blog posts, and dig around the code a bit.
