Access is denied. Check credentials and try again. Group Events with Application Token

I'm getting the following error (Access is denied. Check credentials and try again) when try to execute the following with an application token

https://graph.microsoft.com/v1.0/groups/{omitted}/events?$expand=singleValueExtendedProperties($filter=id eq 'String {00020329-0000-0000-C000-000000000046} Name {omitted}')

The above executes without any issue when using the delegated token. Checked both tokens using https://jwt.io/

and it has Calendars.ReadWrite, also tried with Calendars.Read and still the same issue.

Any pointers would be much appreciated. Thanks

    Hi @AshB

    According to the Graph API, this endpoint does not support application permissions and personal accounts, only delegation permissions.
