How can i call a MS graph API (events) with delegated permissions in Azure AD from console app in .net

Question

i need to call the events graph api to create a meeting link and send it to the attendees
i can call the API using the client flow , which requires the application permissions.
but when only the delegated permissions are granted, there are no roles in token which is generated.
Using the ConfidentialClientApplicationBuilder class to genrate the token
