+  <pre>Returns permissions that a caller has on the specified resource.
+If the resource does not exist, this will return an empty set of
+permissions, not a NOT_FOUND error.
+
+Note: This operation is designed to be used for building permission-aware
+UIs and command-line tools, not for authorization checking. This operation
+may "fail open" without warning.
+
+Args:
+  resource: string, REQUIRED: The resource for which the policy detail is being requested.
+See the operation documentation for the appropriate value for this field. (required)
+  body: object, The request body. (required)
+    The object takes the form of:
+
+{ # Request message for `TestIamPermissions` method.
+    "permissions": [ # The set of permissions to check for the `resource`. Permissions with
+        # wildcards (such as '*' or 'storage.*') are not allowed. For more
