Not able to get GraphQL subscriptions working with graphql codegen

I am currently trying to set up a subscription using graphql codegen types.

import { Context } from '../context'
import { SubscriptionResolvers } from '../../generated/graphql'


export const Subscription: SubscriptionResolvers = {
  scoreUpdated: {
    subscribe: (_parent, _args, context: Context) => {
      return context.pubsub.asyncIterator(NEW_POINT)

The error I’m getting when I hover over subscribe is:

Type '(_parent: {}, _args: {}, context: Context) => AsyncIterator<unknown, any, undefined>' is not assignable to type 'SubscriptionSubscribeFn<any, {}, any, {}>'.
  Type 'AsyncIterator<unknown, any, undefined>' is not assignable to type 'AsyncIterable<any> | Promise<AsyncIterable<any>>'.
    Type 'AsyncIterator<unknown, any, undefined>' is missing the following properties from type 'Promise<AsyncIterable<any>>': then, catch, finally, [Symbol.toStringTag]ts(2322)

I’m not sure what I’m missing to get this working. What am I missing?
