Adding SimpleCORS Policy to CloudFront Distribution

[whobutsb]

Hello all! Would someone be able to give me a suggestion on the best way to add the Response headers policy SimpleCORS policy to my CloudFront distribution in my serverless.yml during deployment? Currently I'am manually adding it to my distribution but for ease of deployment it would be great to have it set. I know you can do it in the constructs.extensions array, but just need a hint.

Here is what I currently have:

constructs:
  website:
    type: server-side-website
    assets:
      '/build/*': public/build

I appreciate the help!

I should add I have some JS and CSS resources stored in a S3 bucket being served with CloudFront. I'm currently getting blocked by the CORS policy No 'Access-Control-Allow-Origin' header error, when trying to view my page.
