Im trying to create new user via submit hook.

And hook works, i can create a user if i hardcode the email to functions.
But i want to pass submited EMAIL, and whatever I do i cant access that variables.

SO can someone tell me where and how to access those submited values to be used in a hook for further functions, like creating user.

$processed_fields_values | array | Processed fields values

Can be accessed how?
