In Microsoft Graph I want to return a list of users who have at least one direct report. It is possible in Azure AD, however I can't find any way to do it on Microsoft Graph.
There is no api endpoint that lists these users, I would have thought that I could access the Users endpoint (https://graph.microsoft.com/v1.0/users/) and apply a Filter, along the lines of "directReports like '*'"
but that syntax is invalid, and I can't find any documentation on filtering.
