Where IResolverOptions goes in the latest version?

Hi everyone,

In graphql-tools@4, there is a type definition IResolverOptions being exported.

import { IResolverOptions } from 'graphql-tools'

// ./node_modules/graphql-tools/dist/interface.d.ts
// export interface IResolverOptions<TSource = any, TContext = any, TArgs = any> {
//     fragment?: string;
//     resolve?: IFieldResolver<TSource, TContext, TArgs>;
//     subscribe?: IFieldResolver<TSource, TContext, TArgs>;
//     __resolveType?: GraphQLTypeResolver<TSource, TContext>;
//     __isTypeOf?: GraphQLIsTypeOfFn<TSource, TContext>;
// }

But I can't find it in any @graphql-tools/* packages(i.e @graphql-tools/utils). Is there a same type definition being exported? Or it only exists in graphql-tools@4?
