Enable push notifications to unidentified users

When visitors don't give their email address and are not identified, if they close the page before we answer, they never get our answer. On mobile they often assume that they'll get a notification when we answer. Thus they leave without waiting, thinking if we answer they'll know it.

It would be really helpful if a user could be prompted to authorise push notifications through their browser, and they would receive notifications when they get a reply.

Are you working on adding that feature? Otherwise do you know a workaround to achieve the same result?
