Problem

Web3Auth UserInfo were not exposed after the login

Solution

Added a public userInfo field that can be accessed after the login:

As a simple example, a script can register to the OnLogin event and print the user email, if available.

public void Start()
{
    Web3.OnLogin += OnLogin;
}

private void OnLogin(Account obj)
{
    if(Web3.Wallet is Web3AuthWallet) Debug.Log(((Web3AuthWallet)Web3.Wallet).userInfo?.email);
}
