Hi

We have Provider Host app and deployed in site collection(demo1). Now we are trying to access the App Catalog site in this app using CSOM.

Getting below error while executing query against "AppCatalog" list.

"Access denied. You do not have permission to perform this action or access this resource."

Is there any configuration required to access "App Catalog" site from other application?

Note: The same app was deployed in other site collection with different client and secret ids. And we were able to access the "App Catalog". Permission level is Site collection - Full Control

Thanks,
