I registered an add-in on my SharePoint Online site collection by going to [Site Collection URL]/_layouts/15/AppRegNew.aspx Noted Client ID and Client Secret. Trying to give it FullControl here: [Site Collection URL]/_layouts/15/AppInv.aspx by entering the following XML:
<AppPermissionRequests AllowAppOnlyPolicy="true"> <AppPermissionRequest Scope="Site Collection URL" Right="FullControl" /> </AppPermissionRequests>
On 'Do you trust the app page' it does not ask me to give it Full Control but only the following: Let it share its permissions with other users. Let it access basic information about the users of this site.
What am I missing?
