How can I create a pull request that auto includes associated work item for the commits?

I'm trying to automate post-release processing. I'm running this code:

    pull_request = {
        "title": title,
        "description": description,
        "sourceRefName": "refs/heads/" + source_branch,
        "targetRefName": "refs/heads/" + target_branch,
    }
    response = self._git_client.create_pull_request(pull_request, repository_id=repo_id)

It creates the pull request, but doesn't link any work items (like if I create it in the GUI). When I query the specific commits I can't seem to get the associated work items either, but the GUI is aware of them. Is there an option I need to specify to get this to automatically work, and if not, how can I find the associated work items to build the list myself?

Thanks,

先从 GitClient.create_pull_request 和 issue 中描述的 commit-query path 入手，然后将它们与 Azure DevOps GUI 关联 work item 的方式进行比较。确定 Python API 是否提供选项或检索方法；完成的标准是记录受支持的处理方式，或明确指出 API 缺失的行为。
