CORS Clarification need help: Got CORS error when sending to Integrated Endpoint While Postman success

however same request successfully in cURL version with same auth token

curl --location ‘https://int.api.service.nhs.uk/personal-demographics/FHIR/R4/Patient?birthdate=eq1994-09-08&family=OHUPHONGWATTHANA
–header ‘X-Request-Id: 5244d79c-0eb4-4f9b-9b4c-04c3047be744’
–header ‘Content-Type: application/fhir+json’
–header ‘Authorization: Bearer [token]’

Any suggestions or I am misunderstanding that PDS supposed not to be called from Browser directly?
