How to get notification for candidate mails in 2way Email communication using vanity mail

How to get in-app/email notifications to the recruiter or the hiring team for the candidate response mails in the two way Email communication using the vanity email?

Hi, We have enabled the 'Two way email communications' using the vanity email and was able to test sending the mails and receiving the candidate responses.

But, there were no notifications received when a candidate responds to the mail or sends a mail to the vanity email.

Is there a way we can set up notifications to the recruiter or hiring team when the candidate sends a mail or responds to a mail sent by system or from the vanity email?
