I would like to make three consequential POST requests using MS Graph: (1. Create an Office 365 group; 2. Add the requester as a member of the group; 3. Create an MS Planner Plan, and set the Group from the 1st request as its owner).
I found this nice batching feature, which seems to be available now: https://developer.microsoft.com/en-us/graph/docs/concepts/json_batching ,
but I am not sure how to pass the group ID, generated within the 1st request to the 2nd and a 3rd one, especially given that we do not have a response from the server by the time the call begins.
