Enable CORS not working | WordPress.org

Hi, So I am attempting to get cors enabled for https://nicobolt.com/ to send things to https://app.commercebird.com/. I installed the plugin, cleared my cache, and the CORS tester is saying this: https://cors-test.codehappy.dev/?url=https%3A%2F%2Fnicobolt.com%2F&origin=https%3A%2F%2Fapp.commercebird.com%2F&method=get

This URL will only work for specific domains. This url can only be loaded by pages that match *, *. If you’re trying to load it from a different origin and it’s not working, you’ll need to change it so the access-control-allow-origin header is set to *.

Please advise. Thank you!
