title: Django allauth - Add custom logic after email verification is successful
body: <p>I am creating an application that has a list of <code>Employees</code>, and after a user registers and verifies their email, I create a relationship between the <code>Employee</code> and their <code>User</code> account.</p>
  
  <p>I am using Django all auth, and have the email confirmation on <code>GET</code> set to True. </p>
  
  <p>I am unsure on how I can add logic, so after the <code>GET</code> I perform some operations, find use the email to find the user, etc. </p>
  
  <p>I have created a custom <code>RegisterSerializer</code> before, but since this is a <code>GET</code> instead of <code>POST</code> I wasn't sure if I could do something similar with EmailVerification.</p>
  
  <p>How would I go about adding custom logic for this? </p>
