The footer of automatic messages for GitHub mirror activity says the following:

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at [hidden email] or file a JIRA ticket
with INFRA.

I've replied directly to the email and they did not appear on GH. I guess the feature is not enabled. I think we should enable it. How can we do this?
