Workflow email issue

Hi All,

We have a requirement like a 'Approve/Reject' mail should send for each PR Approval.

We are able to send a mail and able to receive in mail box.

But while replaying(Approving or rejecting the PR) , the result is not reflecting into the application.

In notification mailer setup i found a check box called: Allow Notification response through email

Whether we need to enable Allow notification response by email to receive the email response into the application or any other thing we need to do..

Navigation : notification mailer --> edit
