Hi team,
After developing the app, we tested locally using "zat=true" all the features of the App were working fine but when the same app installed as private app, the azure api which used for authorization throwing error as "Access to XMLHttpRequest at 'https://dev.azure.com/xxxx/_apis/projects?api-version=6.0' from origin 'https://xxx-xxxxx.zendesk.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. "
Thanks,
Suman

Would you be able to show us the code snippet for the corresponding request?
Thanks!
