Can I import GraphQLESTreeNode from somewhere?

[alexeyr-ci]

I'm trying to write a custom rule modelled on an existing one as suggested in https://the-guild.dev/graphql/eslint/docs/custom-rules#more-examples (specifically, to require __typename as a workaround for #1075). However, for complex selectors it looks like GraphQLESTreeNode is needed, and I can't find how I can import it; RubyMine suggests

import { type GraphQLESTreeNode } from '@graphql-eslint/eslint-plugin/cjs/estree-converter';

but then I get

error TS2307: Cannot find module '@graphql-eslint/eslint-plugin/cjs/estree-converter' or its corresponding type declarations
