Creating a Group at project level - GraphGroupCreationContext issue

[arvinatwork]

Just want to verify if this API is ready to be consumed and used or this particular one is still at preview?

Looks like the request body and the model doesn't have the same attributes:
In here, there's a displayName and description:
https://docs.microsoft.com/en-us/rest/api/azure/devops/graph/groups/create?view=azure-devops-rest-5.0#create_a_group_at_the_project_level

But on the client, where it asks for a graphgroupcreationcontext, it only asks for a storagekey. And the warning here states that we shouldn't use this for creation of a group:
https://docs.microsoft.com/en-us/rest/api/azure/devops/graph/groups/create?view=azure-devops-rest-5.0#graphgroupcreationcontext

How can I create a group in a project level given the api above?
