Setup Iterable (https://iterable.com/) webpush <> a Shopify website.

[thg_]

We are working on the web push integration between Iterable (https://iterable.com/) + a Shopify website.

For this setup, we need to add a Firebase Service worker and a Manifest file to the Shopify website but we can not find any way to add these files successfully. Have anyone used the web push service of Iterable and succeeded in setting it up with a Shopify website? 

Thank you!
