Currently the API to get calls from Graph require Application permissions. However, I think it is natural to be able for a person to retrieve their own calls with delegated permissions, just as they ...
We would like to see this as well
Request for a me/callRecords endpoint with delegated permissions
As nielsbrinch said this should be a Delegated permission CallRecords.Read unlike the /communications/callRecords/ which is only Application CallRecords.Read.All
Ideally a GET request to me/callRecords would return a list of call records for the authenticated user.
And then me/callRecords/{id} would return additional details about a specific callRecord
