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

先从 issue 中链接的 Azure DevOps REST endpoint 开始，然后检查 Python API 是否公开了对应的 team-iteration client method。将其 request 和 path 参数与现有的 work-item creation call 进行比较。完成的标准是确认是否可以通过此 API 创建 PI27；如果可以，则记录或演示受支持的 request。
