Create Microsoft Graph Subscriptions for a shared calendar with delegated user permissions
The MS Graph documentation for subscriptions (webhooks) implies that it is possible to create a subscription on a shared calendar with delegated user permissions (not app-only). Currently, this works only with app-only permissions.
I would very much appreciate to create subscriptions to shared calendars also with delegated user permissions.

Can we allow delegated user, having full access to calendar mailbox, to successfully create subscription for changes in calendar events.
As of today, it throws 403 error with following message. (It makes a call to end notification url successfully, but fails to create a valid subscription)
"message": "Operation: Create; Exception: [Status Code: Forbidden; Reason: Forbidden]",
