Infer TRoot and TProcedure for specific procedures (polymorphism) - tRPC

Hello! I'm trying to build a custom hook that returns specific procedures of a router: ```tsx "use client" import { MutationLike, QueryLike } from "@trpc/react-query/shared" import { AnyProcedure, AnyRootTypes } from "@trpc/server/unstable-core-do-not-import" import { trpc } from "@/trpc/client" type RequiredProcedures<TRoot extends AnyRootTypes, TProcedure extends AnyProcedure> = { create: MutationLike<TRoot, TProcedure> edit: MutationLike<TRoot, TProcedure> list: QueryLike<TRoot, TProcedure> details: QueryLike<TRoot, TProcedure> } export function useApi<T extends RequiredProcedures<any, any>>( getRouter: ( router: typeof trpc ) => T extends RequiredProcedures<infer TRoot, infer TProcedure> ? RequiredProcedures<TRoot, TProcedure> : never ) { const router = getRouter(trpc) return { create: router.create, edit: router.edit, list: router.list, details: router.details, } } function Component() { const { create, edit } = useApi((router) => router.admin.product) const mut = create.useMutation() async function handleCreate() { await mut.mutateAsync({}) } } ``` **How can I infer TRoot and TProcedure?** Currently it is typed as `any` in `T extends RequiredProcedures<any, any>`. But of course now my input and output types are also `any`, which I don't want. Any help is appreciated! :) Thanks!
