Enabling Push Notifications
Web push notifications are notifications that can be sent to a user via desktop and mobile web. These alert-style messages slide in at the top or bottom right-hand corner of a desktop screen, depending on the operating system, or appear on a mobile device in a manner nearly identical to push notifications delivered from apps. Website push notifications are delivered on a user’s desktop or mobile screen whenever their browser is open — whether or not the user is on the website. We did an integration with OneSignal to make this possible.All you need to do is retrieving the App ID and paste it directly in [Marketing Tools] > [Integrations Setup] > [Chat Online]
