After the code is inserted, you have to add Service Worker file to the root folder of your website. To do so, go to website management in our platform and download the following zip by click on Download Service Worker.
Finally unpack zip and upload sarepush-worker.js file to the top-level root of your website. Depending on how your website is hosted, you may need to contact administrator or developer to help you copy this file to your website.
If you are integrating SAREpush into a site with an existing service worker (like a PWA), you may have to merge service workers.
