Teams clone API
According to the documentation there is a clone graph API which will allow to clone a team however the result of the POST call is empty. It would be better that the POST call should return the guide of a team/group which is going to be created.
Also the doc mentions that the cloning is a long time operation and in order to check if the cloning is complete, make the GET calls... However it doesn't mention which GET call and call what??
Here is the link of the preview API documentation:
