An app ID is present in 'http:///_layouts/15/AppPrincipals.aspx' but the same ID is missing from the SharePoint Catalog's 'App Permissions'. The app ID can also be seen under 'Site App permissions' from Site settings. Can someone please let me know how can I add the app ID to 'App permissions'?
Thank you in advance. Any help is greatly appreciated.
