Calendars.Read.Shared

Allows the app to read events in all calendars that the user can access, including delegate and shared calendars.

Merill's Note

For an app to access data in Microsoft Graph, the user or administrator must grant it the permissions it needs. This article lists all the Microsoft Graph APIs and your tenant data that can be accessed by the application (vendor/developer) if you consent to the Calendars.Read.Shared permission.

If you need to create an audit report of the permissions granted to all the apps in your tenant, you can run the Export-MsIdAppConsentGrantReport command. See How To: Run a quick OAuth app audit of your tenant
