+  <pre>Returns the permissions that a caller has on the specified note or
+occurrence resource. Requires list permission on the project (for example,
+"storage.objects.list" on the containing bucket for testing permission of
+an object). Attempting to call this method on a non-existent resource will
+result in a `NOT_FOUND` error if the user has list permission on the
+project, or a `PERMISSION_DENIED` error otherwise. The resource takes the
+following formats: `projects/{PROJECT_ID}/occurrences/{OCCURRENCE_ID}` for
+`Occurrences` and `projects/{PROJECT_ID}/notes/{NOTE_ID}` for `Notes`
+
+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
+        # information see

+
+  x__xgafv: string, V1 error format.
+    Allowed values
+      1 - v1 error format
+      2 - v2 error format
+
+Returns:
+  An object of the form:
+
+    { # Response message for `TestIamPermissions` method.
+    "permissions": [ # A subset of `TestPermissionsRequest.permissions` that the caller is
+        # allowed.
