I'm creating a console application that will upload files to a SPO site collection. I'm registering a SharePoint app using /Appregnew.aspx page and obtain ClientID and ClientSecret and use it on my console application. I need this console application to work on any of the site collection in SPO tenant.
If I want to use this console application in another site collection within the same tenant, do I need to register a SharePoint app in the new site collection and obtain the ClientID and ClientSecret for that site collection as well?
What's the scope of a SharePoint app registered in SPO? is it tenant level or site collection level?
