+ * you can use to render your UI.
+ *
+ * @param baseOptions options that will be passed into the query, supported options are listed on: https://www.apollographql.com/docs/react/api/react-hooks/#options;
+ *
+ * @example
+ * const { data, loading, error } = useGetReservationPermissionsQuery({
+ *   variables: {
