+<!--
+    This policy converts the results of an oracle cloud rest api to an 'odata-like format'.
+    The items element is renamed to value.
+    An '@odata.nextlink' is generated using the count and offset received from oracle and added to the output.
+    With these updates, the oracle api can be called from azure logic apps and PowerAutomate
+    with the paging option enabled and Logicapps will iteate through all the pages for you
