Add Group members & owners delta link
The delta link is actually available for Users and Groups, but not for group members and group owners.
It's not unusual for a tenant to have groups with tons of members each, so, a delta link to get only changes (members added, changed or removed), would be massively useful.
The "DeltaMembers" property available from groups, by using the delta, it's not useful for this matter because it' s only populating the ID property and, also, you are not able to see if that ID is related to an owner or a member.
Looking forward to see the feature available for V1 api.
Currently the groups api includes the possibility to use the delta. Applying the $extend=members it's possibile to retrieve the @deltaMembers collection only exposing the Id and @removed in case of removed member. By using the @deltaMember property there are no chances to understand if the member is an owner or not, so, the Only way to get a consistent collection of members and owners is to invoke the apis group/groupid/members and group/groupid/owners. For these 2 endpoints the delta link is not available, not even a Next link. It would be Extremely helpful to bind the @deltaMembers property with additional infos as IsOwner, userprincipalName, etc.. to get only the members and owner changes straight from groups api with no need to invoke 2 additional endpoints for members and owners.
