How to add Access-Control-Allow-Origin to header in odoo 15

Question

I am getting error shown below:
Access to fetch at 'http://my-domain.com ' [1] from origin 'http://127.0.0.1:5502' 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.
Any idea where I can add CORS to allow every host so I will never see that error again!
