+Example:
+
+```python
+result = ak_call_policy("test-policy")
+# result is a PolicyResult object, so you can access `.passing` and `.messages`.
+# Starting with authentik 2023.4 you can also access `.raw_result`, which is the raw value returned from the called policy
+# `result.passing` will always be a boolean if the policy is passing or not.
+return result.passing
