Microsoft Graph API onlineMeetings endpoint should support userPrincipal

Hi,

currently the endpoint for working woth online meetings only support "me" or "users/id". It would be very helpfull if we could use the userPrincipalName eg. "first.last@company.com" as other endpoints do support.

Especially in combination with impersonation and admin consent this would be an awesome feature.

Thanks in advance

Florian
