OneSignal setup with Webflow

I am setting up OneSignal with my Webflow site to send push notifications, however it is not working on Chrome (seems to be working on all other browsers).

This is the error message:

'Access to fetch at ‘’ from origin ‘’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled.

The server setup is not allowing to fetch the URL of OneSignal like shown there. You can find more details of it at the following URL.

Cross-Origin Resource Sharing (CORS) - HTTP | MDN

Has anyone else had this problem and managed to get it to work on Chrome?
