I am trying to add push notifications on my website by subscribers.com . I have installed the code via google tag manager, then it says to install some service worker (firebase-messaging-sw) in the root directory of my website.
Unfortunately, adding a service worker or any file in the root directory is not supported at the moment.
Please allow it. Push notifications in browsers are getting very common. Wix should support it too.
Hope to hear some positive reply soon.
