Example of how to use CORS with Cloudflare access to pass credentials to a backend. Replace all .community.cyberjake.xyz with your domain.

Need the following:

Cloudflare Policies:

Backend:

Cloudflare tunnel token with public hostnames as shown below.

Edit the cors settings in backend/index.js to match your origin.
