GaTech QCF Interview Invitation link

Hi Guys,
I got my interview invitation yesterday and there is a button that says Accept or Reject. I thought I have to click the button to inform the school that I would take the interview but then the email disappeared, I no longer have the invitation link to the interview. May I ask if I would get the link again when it is close to the scheduled time? or do I have to ask for another link? Thank you, guys!
