How to add new iteration to ADS project

Hello, I have an Azure DevOps project with multiple iteration paths:

If I use this Azure Python API to create a new work item and set /fields/System.IterationPath to have a value that already exists like RTC-ADS\PI28\Sprint 28-3 it will create the work item with no issue.

But if I try to create a work item with an iteration that does not yet exist such as RTC-ADS\PI27 it will fail with an error

ERROR:root:Error creating ADS work item: TF401347: Invalid tree name given for work item -1, field 'System.IterationPath'.

I could create PI27 manually in my Azure Project settings, but is there a way I can use this Azure Python API to create a new iteration value for PI27 by making a POST request or something?

I have found documentation supporting how to do so I believe:
https://docs.microsoft.com/en-us/rest/api/azure/devops/work/iterations/post-team-iteration?view=azure-devops-rest-6.0

But is it possible to add a new iteration value using this API? Thanks

Start with the Azure DevOps REST endpoint linked in the issue, then check whether the Python API exposes a corresponding team-iteration client method. Compare its request and path parameters with the existing work-item creation call. Done means confirming whether PI27 can be created through this API and documenting or demonstrating the supported request if it can.
